Tripartite motif-containing (TRIM) superfamily proteins are critical in a variety of biological processes in innate immunity and are important for eradication of invading pathogens [52,58,67] ... | |||
| tripartite motif containing 38 (2.3.2.27 RING-type E3 ubiquitin transferase) |
TRIM38 catalyses the ubiquitination of Lys48 of the Toll-like receptor (TLR) adaptor protein TICAM1 (commonly referred to as TRIF) which mediates its proteosomal degradation. This action has been shown to inhibit TLR3-driven type I interferon signaling of the innate immune response [74] ... | |||

| GtoPdb receptor name (family) | Process Association Comments | GO Associations | Immunopharmacology Comments | |
| AXL receptor tyrosine kinase (Type XI RTKs: TAM (TYRO3-, AXL- and MER-TK) receptor family) |
All three TAM family receptor tyrosine kinases are involved in regulating inflammatory responses through a negative feedback loop. Specifically, AXL-Gas6 signalling is reported to induce autophagy in murine macrophages via inhibition of the NLRP3 inflammasome, an effect which reduces hepatic inflammation in a mouse model [23] ... | |||
| herpes virus entry mediator (Immune checkpoint catalytic receptors, Tumour necrosis factor (TNF) receptor family) |
HSV viral envelope glycoprotein D (gD) binds to this protein and thereby gains entry to the cell. HVEM binds to several TRAFadaptor proteins to mediate intracellular signalling and activation of the immune response. | |||
| KIT proto-oncogene, receptor tyrosine kinase (Type III RTKs: PDGFR, CSFR, Kit, FLT3 receptor family) |
Stem cell factor (SCF) and its receptor KIT (c-KIT) play an essential part in mast cell biology. In addition to CSF/KIT-mediated regulation of mast cell development, proliferation and survival, KIT is also reported to be involved in the adhesion of mast cells to human airway epithelial cells (a homing and adhesion role), suggesting a mechanism that could be targeted for anti-asthmatic potential [21] ... | |||
| MET proto-oncogene, receptor tyrosine kinase (Type X RTKs: HGF (hepatocyte growth factor) receptor family) |
The leucine-rich repeat (LRR)-containing protein InlB of Listeria monocytogenes is reported to mediate bacterial entry in to non-phagocytic host cells by binding to the MET proto-oncogene, receptor tyrosine kinase (MET, or hepatocyte growth factor receptor, HGFR) [6] ... | |||
| OX40 (Tumour necrosis factor (TNF) receptor family) |
The OX40/OX40L axis is involved in late T cell costimulatory signalling and both partners are transiently expressed following antigen recognition. This checkpoint is particularly important for sustaining the effector function of Th1 and Th2 T cells. Blocking OX40/OX40L is reported to prevent the development of disease in in vivo autoimmune and inflammatory disease models [72] ... | |||
| TYRO3 protein tyrosine kinase (Type XI RTKs: TAM (TYRO3-, AXL- and MER-TK) receptor family) |

| amyloid P component, serum (Serum pentraxins) |
Serum amyloid P or pentraxin 2 is a multi-function circulating plasma protein. It exhibits activity as a soluble pattern recognition receptor of the innate immune system, that can bind DNA and histones when these are released from damaged cells. A recombinant form of human pentraxin 2 (PRM-151; Promedior) has been reported as an anti-fibrotic immunomodulator [15] ... |

CD4 is being targeted for clinical utility in inflammatory diseases like rheumatoid arthritis (RA), neoplasms derived from T helper cells (T cell lymphomas and related malignancies), and for anti-HIV potential. Depending on the design of CD4 targeting antibodies, they can produce immunosuppressive effects via activation of Tregs and induction of tolerance, block HIV binding to CD4 to prevent HIV infection, or induce depletion of CD4+ T cells by apoptosis, ADCC, or CDC [34,68] ... | |||

| CD86 (Other immune checkpoint proteins, CD molecules) |
CD86 (B7-2) is a type I membrane immunoglobulin. It is expressed on antigen-presenting cells and in association with CD80 provides the costimulatory signal necessary for T cell activation and survival. CD86 interacts with CD28 or CTLA-4 on T cells.
