Multiple immune and neural cell types

The term 'Multiple immune and neural cell types' refers to a broad biological context involving various cellular populations within the immune and nervous systems, rather than a specific molecular target such as a protein, enzyme, or receptor. In therapeutic development, a target is typically defined as a discrete molecular entity—most commonly a protein—that can be modulated by a drug to achieve a clinical outcome (Santos et al., Nature Reviews Drug Discovery, 2017). Because this term encompasses a wide array of distinct cell types, such as T-cells, B-cells, neurons, and glia, it lacks the specificity required for molecular classification, drug interaction profiling, or mechanism of action assignment. While certain classes of drugs, such as sphingosine-1-phosphate (S1P) receptor modulators or certain integrin inhibitors, are known to act on receptors expressed across both immune and neural compartments, the 'target' in those instances is the specific receptor molecule itself. Consequently, this entry is classified as incorrect for the purposes of structured target identification. It likely represents a descriptive field or a placeholder for the tissue distribution of a target rather than the target itself.
