Mouse (Murine) Complement Component 3a Receptor 1 (C3AR1) interaction partners

1. Development of burn-induced mechanical allodynia, thermal allodynia, weight bearing changes and edema was assessed in C3aR(-/-), C5aR1(-/-) and C5aR2(-/-) mice and compared to their wild type controls over three days. Burn-induced mechanical allodynia, thermal allodynia and weight bearing changes developed normally C3aR(-/-), C5aR1(-/-) and C5aR2(-/-) mice.

2. Complement component 3a receptor 1 role in the lung cancer progression.

3. The complement 3a receptor (C3aR1) participates in microglial signaling under pathological conditions and was recently shown to be activated by the neuropeptide TLQP-21.

4. whilst the C3aR modulates some elements of disease pathogenesis, overall it is not critical in effector responses and glomerular injury caused by autoimmunity to MPO

5. study provided detailed insights into the C3aR expression pattern in immune and stromal cells under steady-state conditions

6. proposal that C3aR activation alters the tumor inflammatory milieu, thereby promoting tumor growth

7. The roles of C3, CfB, and C3a receptor in the severity of S. aureus induced septic arthritis are reported.

10. these findings suggest a critical role for C3a through autocrine/paracrine induction of C3aR in the pathogenesis of cigarette smoke-induced sterile inflammation and provide new therapeutic targets for the treatment of emphysema.

11. C3a/C3aR signaling during host immune response suppresses Fas expression and caspase-3 activity while increasing Bcl-2 proto-oncogene protein expression, providing protection to myeloid and lymphoid cells against L. monocytogenes-induced apoptosis.

12. This study indicated that C3a and C5a-mediated functions are not critical to the development of experimental autoimmune uveitis.

13. The binding of TLQP-21 to C3AR1 not only has effects on signaling but also modulates cellular functions
