Neural and Immune Tissue

Neural and Immune Tissue refers to broad biological systems and anatomical structures rather than a specific molecular target such as a receptor, enzyme, or ion channel. In the context of drug discovery, a therapeutic target is defined as a discrete molecular entity, typically a protein or nucleic acid, whose activity can be modified by a drug to produce a clinical effect (Santos et al., 2017). While the crosstalk between the nervous and immune systems—often termed neuroimmunology—is central to the pathology of conditions like multiple sclerosis, Alzheimer's disease, and chronic pain, the term itself describes a collection of diverse cell types and organs (NIH, 2023). Consequently, it does not meet the criteria for a canonical therapeutic target because it lacks a specific molecular identity and the specificity required for pharmacological modulation. Effective drug development requires identifying specific proteins within these tissues, such as cytokines, neurotransmitter receptors, or cell surface markers, to ensure selectivity and minimize adverse effects. Targeting an entire tissue system is not a viable pharmacological strategy due to the high risk of widespread off-target interactions and systemic toxicity.
