Although latest studies discovered C3a and gC1q receptors as goals for TLQP-21, its intracellular molecular systems of actions stay generally unidentified. Our goal was (i) to explore the intracellular signaling pathway(s) triggered by JMV5656, a novel derivative of TLQP-21, in Natural264.7 macrophages, and (ii) to assess linkages of these pathways with its purported receptors. JMV5656 stimulated, inside a dose-dependent fashion, a rapid and transient increase in intracellular Ca2+ concentrations in Natural264.7 cells; repeated exposure to the peptide resulted in a lower response, suggesting a possible desensitization mechanism of the receptor. In particular, JMV5656 improved cytoplasmic Ca2+ levels by a PLC-dependent launch of Ca2+ from your endoplasmic reticulum. STIM proteins and Orai Ca2+ channels were triggered and played a crucial part. In fact, treatment of the cells with U73122 and thapsigargin BSF 208075 supplier modulated the increase of intracellular Ca2+ levels stimulated by JMV5656. Moreover, in Natural264.7 cells intracellular Ca2+ raises did not happen through the binding of JMV5656 to the C3a receptor, since the boost of intracellular Ca2+ levels induced by JMV5656 was not affected by specific siRNA against C3aR. In summary, our study provides new indications for the downstream effects of JMV5656 in macrophages, suggesting that it could activate receptors different from the C3aR.
