Hypoxia-responsive synthetic gene circuits to improve safety and potency of CAR T cell therapy for solid tumors.

37 Background: Engineered cell therapies expressing a chimeric antigen receptor (CAR) in human T cells have demonstrated great promise for the treatment of hematological malignancies. However, unique challenges remain in translating the success of CAR T cell therapies to solid tumors, namely: (1) specificity: there are few truly unique antigens present on solid tumors, leading to off-target effects that damage normal tissue and pose safety risks; and (2) suppression: solid tumors develop microenvironments that are immunosuppressive and decrease T cell survival and tumor-directed cytotoxicity. To address these challenges and improve the safety and potency of solid tumor cell therapy, we engineered cells with synthetic genetic circuits containing a previously validated hypoxia biosensor (HBS) that responds to upregulation of the native HIF1α and HIF2α transcription factors by hypoxia, enabling the cells to sense and respond to the hypoxic tumor microenvironment ubiquitous among solid tumors. Methods: We evaluated CAR expression from circuit architectures containing the HBS promoter driving expression of both CAR and native HIF1α, HIF2α, as well as from circuit architectures containing the HBS promoter and our toolkit of synthetic transcription factors and promoters. Circuits were integrated into HEK293 cells via PiggyBac transposon vector to generate stable cell lines. Cells were subsequently cultured in normoxia (21% O2) and hypoxia (1% O2), and harvested for flow cytometric analysis to evaluate CAR surface expression across a three day time frame. Results: We identified novel circuits providing fast reporter output with minimal background signal under hypoxic conditions, and elucidated design rules that enable or restrict amplification of transgene in native HIF1α and HIF2α-containing circuits. We observed differences in CAR transgene expression in hypoxia between circuits containing HIF1α and HIF2α-mediated feedback, suggesting mechanistic differences in regulation of HIF1α and HIF2α when overexpressed. Additionally, we observed greatly amplified transgene expression in circuit topologies containing feedback mediated by our synthetic transcription factor and promoter toolkit compared to native HIF1α and HIF2α-containing circuits and cells constitutively expressing CAR. Conclusions: We present a new therapeutic technology that senses hypoxic environments and enables high-output sense and respond behaviors with therapeutic outputs. We envision that this technology will enable development of safer, more effective cell therapies for solid tumors, as well as provide new biological and mechanistic insights that can inform the future development of hypoxia-responsive cell therapies.

Emerging Trends and Innovations in the Treatment and Diagnosis of Atherosclerosis and Cardiovascular Disease: A Comprehensive Review towards Healthier Aging.

Cardiovascular diseases (CVDs) are classed as diseases of aging, which are associated with an increased prevalence of atherosclerotic lesion formation caused by such diseases and is considered as one of the leading causes of death globally, representing a severe health crisis affecting the heart and blood vessels. Atherosclerosis is described as a chronic condition that can lead to myocardial infarction, ischemic cardiomyopathy, stroke, and peripheral arterial disease and to date, most pharmacological therapies mainly aim to control risk factors in patients with cardiovascular disease. Advances in transformative therapies and imaging diagnostics agents could shape the clinical applications of such approaches, including nanomedicine, biomaterials, immunotherapy, cell therapy, and gene therapy, which are emerging and likely to significantly impact CVD management in the coming decade. This review summarizes the current anti-atherosclerotic therapies' major milestones, strengths, and limitations. It provides an overview of the recent discoveries and emerging technologies in nanomedicine, cell therapy, and gene and immune therapeutics that can revolutionize CVD clinical practice by steering it toward precision medicine. CVD-related clinical trials and promising pre-clinical strategies that would significantly impact patients with CVD are discussed. Here, we review these recent advances, highlighting key clinical opportunities in the rapidly emerging field of CVD medicine.

Detecting rhythmic spiking through the power spectra of point process model residuals.

Objective. Oscillations figure prominently as neurological disease hallmarks and neuromodulation targets. To detect oscillations in a neuron's spiking, one might attempt to seek peaks in the spike train's power spectral density (PSD) which exceed a flat baseline. Yet for a non-oscillating neuron, the PSD is not flat: The recovery period ('RP', the post-spike drop in spike probability, starting with the refractory period) introduces global spectral distortion. An established 'shuffling' procedure corrects for RP distortion by removing the spectral component explained by the inter-spike interval (ISI) distribution. However, this procedure sacrifices oscillation-related information present in the ISIs, and therefore in the PSD. We asked whether point process models (PPMs) might achieve more selective RP distortion removal, thereby enabling improved oscillation detection.Approach. In a novel 'residuals' method, we first estimate the RP duration (nr) from the ISI distribution. We then fit the spike train with a PPM that predicts spike likelihood based on the time elapsed since the most recent of any spikes falling within the precedingnrmilliseconds. Finally, we compute the PSD of the model's residuals.Main results. We compared the residuals and shuffling methods' ability to enable accurate oscillation detection with flat baseline-assuming tests. Over synthetic data, the residuals method generally outperformed the shuffling method in classification of true- versus false-positive oscillatory power, principally due to enhanced sensitivity in sparse spike trains. In single-unit data from the internal globus pallidus (GPi) and ventrolateral anterior thalamus (VLa) of a parkinsonian monkey-in which alpha-beta oscillations (8-30 Hz) were anticipated-the residuals method reported the greatest incidence of significant alpha-beta power, with low firing rates predicting residuals-selective oscillation detection.Significance. These results encourage continued development of the residuals approach, to support more accurate oscillation detection. Improved identification of oscillations could promote improved disease models and therapeutic technologies.

Toward a large-batch manufacturing process for silicon-stabilized lipid nanoparticles: A highly customizable RNA delivery platform

While lipid nanoparticles (LNPs) are a key enabling technology for RNA-based therapeutics, some outstanding challenges hinder their wider clinical translation and use, particularly in terms of RNA stability and limited shelf life. In response to these limitations, we developed silicon-stabilized hybrid lipid nanoparticles (sshLNPs) as a next-generation nanocarrier with improved physical and temperature stability, as well as the highly advantageous capacity for “post-hoc loading” of RNA. Nevertheless, previously reported sshLNP formulations were produced using lipid thin film hydration, making scale-up impractical. To realize the potential of this emerging delivery platform, a manufacturing process enabling multikilogram batch sizes was required for successful clinical translation and deployment at scale. This was achieved by developing a revised protocol based on solvent injection mixing and incorporating other process adjustments to enable in-flow extrusion of multiliter volumes, while ensuring sshLNPs with the desired characteristics. Optimized procedures for nanoparticle formation, extrusion, and tangential flow filtration (TFF, to remove residual organic solvent) currently enable production of 2 kg finished batches. Importantly, sshLNPs produced via the modified large-scale workflow show equivalent physical and functional properties to those derived from the earlier small-scale methods, paving the way for GMP manufacturing protocols to enable vital translational clinical studies.

Clinical applications and perspectives of immune checkpoint inhibitors in oral squamous cell carcinoma

Abstract Immune checkpoint inhibitors (ICIs) promote antitumour immune responses by blocking inhibitory signals expressed by T cells and have significant clinical benefits in the treatment of oral squamous cell carcinoma (OSCC). With the advancement of immunotherapy, an increasing number of ICIs have been developed or are in clinical trial stages. However, drug resistance and immune-related adverse events (irAEs) associated with ICIs have limited the clinical application of immunotherapy in OSCC, and the optimal drug regimen for ICIs and the optimal duration of ICIs administration also deserves to be further discussed. New therapeutic regimens and drug delivery technologies are key to promoting the further development of ICIs. This article elucidates the mechanism of ICIs’ action and presents a review of their clinical applications and current development status in OSCC. Additionally, it summarizes the current challenges and outlines future research directions for ICIs therapy, with the aim of offering fresh insights to researchers.

Biosymbiotic haptic feedback - Sustained long term human machine interfaces

Haptic technology permeates diverse fields and is receiving renewed attention for VR and AR applications. Advances in flexible electronics, facilitate the integration of haptic technologies into soft wearable systems, however, because of small footprint requirements face challenges of operational time requiring either large batteries, wired connections or frequent recharge, restricting the utility of haptic devices to short-duration tasks or low duty cycles, prohibiting continuously assisting applications. Currently many chronic applications are not investigated because of this technological gap. Here, we address wireless power and operation challenges with a biosymbiotic approach enabling continuous operation without user intervention, facilitated by wireless power transfer, eliminating the need for large batteries, and offering long-term haptic feedback without adhesive attachment to the body. These capabilities enable haptic feedback for robotic surgery training and posture correction over weeks of use with neural net computation. The demonstrations showcase that this device class expands use beyond conventional brick and strap or epidermally attached devices enabling new fields of use for imperceptible therapeutic and assistive haptic technologies supporting care and disease management.

Duet playing in dementia care: a new therapeutic music technology

Purpose Supporting the relational worlds of people living with dementia, especially the spousal dyad, is a growing focus in dementia care as is advancing the therapeutic use of music in dementia care. This paper describes a mixed-methods, multi-phase, iterative research study designed to develop the Music Memory Makers (MMM) Duet System, a novel therapeutic music technology, that allows non-musicians to play a personalized repertoire of songs arranged as duets. Methods Following a pilot phase to iteratively assess and refine the MMM Duet System for recreational and therapeutic purposes, multiple sources of data were used to investigate five older spousal dyads’ experiences with the system, two couples living with dementia and three who were not. We assessed perceptions of task difficulty, joint agency, and enjoyment as well as therapeutic benefits associated with enhancing the spousal relationship and sense of couplehood. Results Findings suggest playing meaningful songs together is an enjoyable interactive activity that prompts musical reminiscence, involves joint agency, and supports relationship continuity within a relational, positive approach to dementia care. All couples mastered the task, none evaluated it as “very challenging,” and positive couple interactions were evoked, commonly before and after playing the duets. Conclusions The MMM Duet System is recommended for further research and development as an innovative way to support couples living with dementia with commercial implications, and as a new music technology suitable for use as a research tool.

Ionizing radiation's inherent qualities give numerous benefits, but they can also be harmful. Its usage in medical practice requires an informed decision on the risk-benefit ratio. This choice requires knowledge of radiation in general as well as medical skill in specific. This review investigated the risks associated with radiation, their connection to medicine, and the advancements in diagnostic and therapeutic technologies. Radioactive substances and radiation are used in medicine, research, and diagnosis. The forms of radiation and their varied impacts on medicine, particularly in the treatment and diagnosis of disorders like cancer, were disclosed by our review's conclusions. It has been demonstrated that mistakes in radiation dosage can result in health issues, hence managing radiation must be done carefully both during research and in practice

Mechanisms of myeloid-derived suppressor cell-mediated immunosuppression in colorectal cancer and related therapies.

Severe immunosuppression is a hallmark of colorectal cancer (CRC). Myeloid-derived suppressor cells (MDSCs), one of the most abundant components of the tumor stroma, play an important role in the invasion, metastasis, and immune escape of CRC. MDSCs create an immunosuppressive microenvironment by inhibiting the proliferation and activation of immunoreactive cells, including T and natural killer cells, as well as by inducing the proliferation of immunosuppressive cells, such as regulatory T cells and tumor-associated macrophages, which, in turn, promote the growth of cancer cells. Thus, MDSCs are key contributors to the emergence of an immunosuppressive microenvironment in CRC and play an important role in the breakdown of antitumor immunity. In this narrative review, we explore the mechanisms through which MDSCs contribute to the immunosuppressive microenvironment, the current therapeutic approaches and technologies targeting MDSCs, and the therapeutic potential of modulating MDSCs in CRC treatment. This study provides ideas and methods to enhance survival rates in patients with CRC.

Designing molecules: directing stem cell differentiation.

Stem cells have been widely applied in regenerative and therapeutic medicine for their unique regenerative properties. Although much research has shown their potential, it remains tricky in directing stem cell differentiation. The advancement of genetic and therapeutic technologies, however, has facilitated this issue through development of design molecules. These molecules are designed to overcome the drawbacks previously faced, such as unexpected differentiation outcomes and insufficient migration of endogenous or exogenous MSCs. Here, we introduced aptamer, bacteriophage, and biological vectors as design molecules and described their characteristics. The methods of designing/developing discussed include various Systematic Evolution of Ligands by Exponential Enrichment (SELEX) procedures, in silico approaches, and non-SELEX methods for aptamers, and genetic engineering methods such as homologous recombination, Bacteriophage Recombineering of Electroporated DNA (BRED), Bacteriophage Recombineering with Infectious Particles (BRIP), and genome rebooting for bacteriophage. For biological vectors, methods such as alternate splicing, multiple promoters, internal ribosomal entry site, CRISPR-Cas9 system and Cre recombinase mediated recombination were used to design viral vectors, while non-viral vectors like exosomes are generated through parental cell-based direct engineering. Besides that, we also discussed the pros and cons, and applications of each design molecule in directing stem cell differentiation to illustrate their great potential in stem cells research. Finally, we highlighted some safety and efficacy concerns to be considered for future studies.

Current status and breakthroughs in treating advanced non-small cell lung cancer with EGFR exon 20 insertion mutations.

Recently, targeted therapy and immunotherapy have emerged as effective treatment options for non-small cell lung cancer (NSCLC). This progress has been facilitated by the rapid development of diagnostic and therapeutic technologies and the continuous research and development of new drugs, leading to a new era in precision medicine for NSCLC. This is a breakthrough for patients with common mutations in the human epidermal growth factor receptor (EGFR) gene in NSCLC. Consequently, the use of targeted drugs has significantly improved survival. Nevertheless, certain rare genetic mutations are referred to as EGFR exon 20 insertion (ex20ins) mutations, which differ in structure from conventional EGFR gene mutations, namely, exon 19 deletion mutations (19-Del) and exon 21 point mutations. Owing to their distinct structural characteristics, patients harboring these EGFR ex20ins mutations are unresponsive to traditional tyrosine kinase inhibitor (TKI) therapy. This particular group of patients did not fall within the scope of their applicability. However, the activating A763_Y764insFQEA mutation elicits a more pronounced response than mutations in the near and far regions of the C-helix immediately following it and should, therefore, be treated differently. Currently, there is a lack of effective treatments for EGFR ex20ins mutations NSCLC. The efficacy of chemotherapy has been relatively favorable, whereas the effectiveness of immunotherapy remains ambiguous owing to inadequate clinical data. In addition, the efficacy of the first- and second-generation targeted drugs remains limited. However, third-generation and novel targeted drugs have proven to be effective. Although novel EGFR-TKIs are expected to treat EGFR ex20ins mutations in patients with NSCLC, they face many challenges. The main focus of this review is on emerging therapies that target NSCLC with EGFR ex20ins and highlight major ongoing clinical trials while also providing an overview of the associated challenges and research advancements in this area.

But unlike other specialties, ultrasound became the driving force behind the development and implementation of interventional technologies in the treatment of diseases of the musculoskeletal system. In recent years, ultrasound-guided injections have gained significant popularity, as they have given an advantage in accuracy compared to injections without such navigation. The purpose of our study was the development of ultrasound navigation accesses to the hip and knee joints for the interventional application of regenerative technologies in their pathology. The material for the study was the results of ultrasound examination of the hip and knee joints of 486 patients with diseases and injuries of the hip and knee, who were treated in the scientific and practical department of tissue and cell therapy of the State Institute of Traumatology and Orthopedics of the National Academy of Medical Sciences of Ukraine in the period from 2016 to 2023. The results. The following accesses to the knee joint under ultrasound navigation have been developed: suprapatellar longitudinal access for injections into the quadriceps tendon and patellofemoral joint, suprapatellar longitudinal access with knee bending for injections into the upper turn of the knee joint, infrapatellar longitudinal access for injections into the patellar ligament and deep infrapatellar bursa, infrapatellar transverse access for injections into Hoffa’s fat pad, lateral longitudinal access with knee bending for injections into the lateral meniscus, medial longitudinal access with bending in the knee for injections in the medial meniscus, medial transverse access for injections in the medial part of the joint space, lateral transverse access with bending in the knee joint for injections in the lateral part of the joint space, lateral longitudinal access for performing injections in the collateral fibular ligament, medial longitudinal access for performing injections in the collateral tibial ligament, infrapatellar diagonal access for performing injections in the “crow’s foot” area of the knee joint, infrapatellar medial longitudinal access for performing other injection into the medial meniscus and joint capsule, lateral longitudinal access for injections into the tendons of the biceps femoris and hamstrings. The following accesses have been developed for the hip joint: anterior longitudinal access for performing injections in the subcapsular-cervical space, anterior diagonal access for performing injections in the acetabular labrum, capsule-ligament apparatus of the hip and tendon of the rectus femoris muscle, lateral longitudinal access for performing injections in the paratrochanteric region. Conclusions. 13 ultrasonic navigation accesses have been developed for the administration of biotechnological products into the knee joint and 3 – into the hip join, which allow not only to detect damaged intra-articular and para-articular structures of the knee and hip joints, but also to deliver an orthobiologics products directly to them for maximum regenerative effect.
