Immune pathways and cells

Immune pathways and cells encompass the integrated network of signaling cascades and specialized cellular subsets, such as T cells, B cells, and myeloid cells, that maintain host homeostasis and defense (Janeway's Immunobiology, 2016). These pathways involve complex interactions between cytokines, chemokines, and cell-surface receptors to coordinate innate and adaptive immune responses against pathogens and malignant cells (Nature Reviews Immunology, 2018). In a healthy state, the system effectively distinguishes between self-antigens and foreign threats, but dysregulation can lead to chronic inflammation or autoimmune disorders (Cell, 2021). In oncology, tumors often exploit these pathways to create an immunosuppressive microenvironment, leading to immune evasion (NEJM, 2020). While many therapeutic agents target specific nodes within this system—such as checkpoint inhibitors or kinase inhibitors—the term itself describes a broad physiological category rather than a single druggable molecular entity. Consequently, it is classified as an incorrect target designation for specific drug-receptor interaction modeling due to being overly broad and non-specific.
