The violent construction of silence(s): The case of targeted killings in North Waziristan, Pakistan

Objeotive To investigate the target killing effect off Raji cells with anti-CD20scFv-FcCD28/ζ gene chimeric T lymphocytes and the activation of T lymphocytes and further approach the mechanism of gene chimeric T lymphocytes target killing lymphoma cells.Methods The plasmids were transfected into retrovirus-packed PA317 cell lines by liposome.The supernatant wills collected from successfully transfected PA317 cells,then co-cultured with T lymphocytes,screening with G418 800μg/ml for 1 week.T-lymphocytes co-culture was grafted with Rail cell lines.the Bcl-2 of Raij cells were examined at timecourse by FACS.the level of IL-10 and IFN-γ was determined by ELISA.Results The Bcl-2 rate had obviously decreased within 24 h in Raii cells.the decreased amplitude was from 98.43%to 38.45%within 72 h.which is significant higher than that in control group and blank group.We found the IL-10 was 100.30 pg/ml in test group at 72 h,which was lower than that in control group(210.88 pg/ml)and blank group (286.71 pg/ml).At the same time IFN-γ(1487.23 pg/ml)was higher than that of other groups.Conclusion Anti-CD20-mediated T cells target lysis Rail cells does not require CD28 costimulation.T cells can enhanced inhibited the IL-10 secretion of Raji by CD28 and CD3ζ costimulation,and also decrease the Bcl-2 of Raji,thereby it accelerates the target cell lysis.CD28/ζ can completely activate T cell without exogenous B7/CD28 costimulation,which furthermore promote T lymphocyte secretion IFN-γ and can also enhance the targeted killing activity of T lymphocytes to Rail cells.

The volume concludes with an exchange between the authors, directly engaging with the others’ respective argument. In this penultimate chapter, Meisels briefly responds and replies to the arguments raised by Waldron against targeted killing. Meisels emphasizes some points of agreement between the two authors: Their commitment to the right to life and the laws of armed conflicts, and their non-pacifist and non-absolutist position on targeted killing. She reemphasizes their points of disagreement, such as the authors’ very different use of analogies, particularly in determining the normative framework for discussing targeted killing (war/armed conflict), their differing views on possible proliferation of target killing, as well as disagreements over precedents and particular cases.

On 30 September 2011, the US citizen Anwar al-Awlaki was killed in Yemen in what has become the most controversial incident of US ‘targeted killing’, or, as its critics would prefer, of the US practice of ‘extrajudicial executions’. This controversy over wording expresses a profound disagreement over the legal status of the US drone program. Target killing suggests that the drone program may be legally regulated. Extrajudicial execution suggests that it falls outside the realm of legality. This article does not seek to settle which terminology is the most appropriate. Instead it analyses the legal expertise struggling to do so and its implications. More specifically, it focuses on the processes through which drones constitute the legal expertise that constitutes the drone program as one of targeted killings and of extrajudicial executions; that is, on a process of co-constitution. Drawing theoretical inspiration from and combining new materialist approaches (especially as articulated by Bruno Latour) with the sociological approach of Pierre Bourdieu, the article shows that drones have ‘agency’ in the ‘field’ of legal expertise pertaining to the drone program. Drones are redrawing the boundaries of legal expertise both by making associations to new forms of expertise and by generating technological expert roles. They are also renegotiating what is valuable to expertise. Drones are making both transparency and secrecy core to expertise. However, and contrary to what is often claimed, this agency does not inescapably lead to the normalization of targeted killings. The article therefore concludes that acknowledging the agency of drones is important for understanding how legal expertise is formed but especially for underscoring the continued potential for controversy and politics.

This paper presents the case of endogenously generated community resilience to violent extremism by discussing the formation and functioning of community-based youth organizations (CBYOs) in post-conflict North Waziristan. In doing so, the paper deciphers a micro-sociological phenomenon underlining the community (re)organization through their new mode of interaction and connectedness, sustaining a resilient social change in the post-conflict setting. The research employed a qualitative research design using the ‘mini-ethnographic’ case study method. For the purpose, twelve CBYOs and members of the local youth were interviewed, allowing for a subjective assessment of the emergence and sustenance of (community) resilience to violent extremism. Offering unique sociological perspectives on a post-conflict context, the study uncovers the community resilience generated through the formation of CBYOs by educated youth in North Waziristan. The social activities and engagement by youth, through education and awareness campaigns, are instilling a social change (by replacing the old ideas and customs with new ones) that aims at creating a peaceful society.

Targeted Killing of AML Cells By Bispecific Antibody Armed Activated T Cells

Cervical cancer is a major cause of cancer death in women worldwide. Targeting human papillomavirus (HPV) viral oncoproteins E6 and E7 is a new strategy for cervical cancer immunotherapy and has been associated with resolution of HPV-induced lesions. How to efficiently induce T cell target killing of HPV infected cervical cancer is of great potential benefit for cervical cancer treatment. Fusion protein containing the extra domain A (EDA) from fibronectin, a natural ligand for Toll-like receptor 4 (TLR4), and HPVE7 (EDA-E7) has been shown to efficiently induce dendritic cells maturation and trigger specific antitumor CD8+ T cells response in mice. In this study, we constructed EDA-E7 fusion protein of human origin and tested its function in dendritic cell maturation as well as antitumor T cell response. We found that EDA-E7 could be efficiently captured by human PBMC derived dendritic cells (DCs) in vitro and induce DCs maturation. Importantly, this effect could work in synergy with the TLR ligand anti-CD40 agonist, polyinosinic-polycytidylic acid [poly (I:C)], R848, and CpG2216. EDA-E7 matured DCs could activate T cells and trigger an anti-tumor response in vitro. Single cell RNA sequencing and T cell targeted killing assay confirmed the activation of T cells by EDA-E7 matured DCs. Therefore, therapeutic vaccination with EDA-E7 fusion protein maybe effective for human cervical carcinoma treatment.

The period known as the “War on Terror” has prompted a revival of interest in the idea of moral dilemmas and the problem of “dirty hands” in public life. Some contend that a policy of targeted killing of terrorist actors is (under specified but not uncommon circumstances) an instance of a dirty-handed moral dilemma – morally required yet morally forbidden, the least evil choice available in the circumstances, but one that nevertheless leaves an indelible moral stain on the character of the person who makes the choice. In this chapter we argue that, while dirty hands situations do exist as a persistent problem of political life, it is generally a mistake to classify policies of target killing (such as the current US policy) as examples of dirty hands. Instead, we maintain, such policies, if justified at all, must ordinarily be justified under the more exacting standards of just war theory and its provisions for justified killing – in particular the requirement that (with limited and defined exceptions) non-combatants be immune from intentional violence. Understanding this distinction both clarifies the significance of dirty hands as a moral phenomenon and also forestalls a set of predictable and all-too-easy appropriations of the concept to domains it was never intended to address.
