Immune function pathways

Immune function pathways represent the integrated network of biochemical signals and cellular processes that govern the body's defense against pathogens and endogenous threats (NIH, 2021). These pathways are broadly categorized into innate and adaptive immunity, involving diverse molecular components such as Toll-like receptors, cytokine receptors, and T-cell receptors (Janeway et al., 2001). In the context of pharmacology, 'Immune function pathways' is a collective term rather than a specific therapeutic target, as it encompasses a vast array of distinct proteins and enzymes (Nature Reviews Drug Discovery, 2020). Therapeutic intervention typically targets specific nodes within these pathways, such as the JAK-STAT signaling cascade or PD-1/PD-L1 checkpoints, to treat conditions ranging from rheumatoid arthritis to metastatic melanoma (StatPearls, 2023). Dysregulation of these pathways can lead to either immunodeficiency or pathological inflammation and autoimmunity (PubMed, 2022). Because this term describes a biological system rather than a single molecule, it is considered a broad therapeutic area rather than a discrete drug target.
