Abstract:
Immunomodulating effects of synthetic peptides Vilon (Lys-Glu), Epithalon (Ala-Glu-Asp-Gly), and Cortagen (Ala-Glu-Asp-Pro) and possible involvement of the sphingomyelin signal transduction pathway in their effects in mouse thymocytes were studied. Vilon produced the most potent comitogenic effect on thymocyte proliferation and modulated comitogenic activity of interleukin-1b. Epithalon was less potent, while Cortagen produced no such effects. Vilon produced a more pronounced stimulatory effect on sphingomyelinase activity in mouse thymocyte membranes compared to Epithalon and Cortagen.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
