Broader immune cell populations

Broader immune cell populations refers to the diverse array of leukocytes, including lymphocytes (T, B, and NK cells), myeloid cells (monocytes, macrophages, and granulocytes), and dendritic cells, that collectively coordinate the body's immune response (Janeway et al., Immunobiology, 2001). This term does not define a single molecular target but rather a systemic cellular network involved in both innate and adaptive immunity (NIH, National Institute of Allergy and Infectious Diseases). In clinical practice, targeting these populations is a common strategy for treating autoimmune diseases, preventing organ transplant rejection, and managing hematologic malignancies through the use of broad-spectrum immunosuppressants or chemotherapy (StatPearls, Immunosuppression, 2023). Drugs like corticosteroids or antimetabolites interact with these populations by inhibiting global cell proliferation or signaling pathways common to multiple lineages (NCBI, PubChem). Because these therapies lack specificity, they often lead to significant safety concerns, such as increased susceptibility to opportunistic infections and myelosuppression (PubMed, PMC7151812).
