"We demonstrate that hCD4-primed gp 120IIIB interacts with CXCR4 receptors expressed by postnatal mouse neural progenitor cells and elicits robust Ca2+ signals. The chemokine SDF-1 acted as a chemoattractant and a mitogenic stimulus for these neural progenitor cells," scientists in the United States report.
"Although hCD4/gp120 was not able to produce chemoattraction or increase proliferation, it completely blocked the ability of SDF-1 to produce these effects.
"Thus, gp120 can act both as an agonist and de facto antagonist of CXCR4-mediated signaling in...
