The role of calcium homeostasis in modulating the immune response in cancer and infectious diseases

Abstract

Calcium homeostasis is a pivotal determinant of physiological processes, particularly in cellular signaling and immune system regulation. This balance is crucial for modulating immune responses in the context of both infectious and oncological diseases. Disruptions in calcium homeostasis have been shown to influence disease progression, immune efficacy, and treatment outcomes. Our study investigates the critical role of calcium homeostasis in shaping the immune response to cancer and infectious diseases through a comprehensive literature review. The electronic databases Scopus, Google Scholar, and PubMed were utilized to gather relevant studies, identified using key terms such as "calcium homeostasis," "immune response," "cancer," and "infectious diseases." Emerging evidence underscores that calcium levels directly impact immune cell function, including the activation of immune effector cells, cytokine production, and the orchestration of the overall immune response. These processes are critical to the body's ability to combat infections and malignancies. Aberrant calcium signaling may lead to compromised immune defense mechanisms, negatively affecting the outcomes of therapeutic interventions. In cancer, for example, altered calcium homeostasis can suppress immune surveillance, while in infectious diseases, it can hinder the immune system's capacity to clear pathogens. Our review highlights that the pathophysiology of both cancer and infectious diseases is tightly interwoven with calcium regulation, suggesting a promising avenue for therapeutic targeting. Modulating calcium homeostasis may enhance immune functionality, thereby improving treatment efficacy. By restoring calcium balance, novel therapeutic approaches could be developed to optimize immune responses and bolster clinical outcomes across a range of diseases. Further research is warranted to elucidate the precise molecular mechanisms linking calcium homeostasis and immune regulation, with the goal of refining future therapeutic strategies. Maintaining calcium equilibrium is thus essential for the advancement of effective treatments in both cancer and infectious disease contexts.
