Multiple immune and stromal cells

"Multiple immune and stromal cells" is not the canonical name of a single molecular target or receptor but rather refers to a broad and heterogeneous collection of cell types within tissues. **Immune cells** encompass various subtypes such as lymphocytes, macrophages, dendritic cells, and others responsible for immune surveillance and response. **Stromal cells** are non-parenchymal connective tissue cells (including fibroblasts, endothelial cells, mesenchymal stromal cells, and pericytes) that form the structural scaffold of tissues and organs and play essential roles in tissue homeostasis, microenvironment organization, and modulation of immune responses[1][4][5][6][7]. This entry is **not a valid therapeutic target** because it fails to designate a specific, actionable molecule, receptor, or protein. Instead, it ambiguously combines broad classes of both immune and supportive/stromal cell types, each of which may have unique functions, markers, and disease associations. For structured biological and pharmacological information as requested, a precise, well-defined individual target (such as "Programmed cell death protein 1 (PD-1)" or "Fibroblast activation protein (FAP)") is required, not a mixed or group description.
