Immune cell surface receptors and immune system proteins

Immune cell surface receptors and immune system proteins encompass a broad array of molecules, including Cluster of Differentiation (CD) markers, cytokine receptors, and pattern recognition receptors (PRRs) (Janeway et al., 2001). These proteins are fundamental to the immune system's ability to distinguish between self and non-self, facilitating processes such as antigen presentation, T-cell activation, and the inflammatory cascade (UniProt, 2024). Dysregulation of these pathways is a hallmark of numerous pathologies, including autoimmune disorders like rheumatoid arthritis and various malignancies where immune checkpoints are exploited by cancer cells (PubMed, 2023). Therapeutic intervention often involves monoclonal antibodies or small molecules that either block inhibitory signals or enhance stimulatory ones to restore immune homeostasis (StatPearls, 2024). However, because this term refers to a functional category rather than a specific protein or complex, it does not meet the criteria for a single therapeutic target (NIH, 2024). Targeting these molecules requires high specificity to avoid systemic toxicity or unintended immunosuppression. This category is generally considered too broad for precise pharmacological profiling or clinical trial mapping.
