Intriguing results were reported from experiments showing the mRNA expression of the RXFP1 gene: WI-38 fibroblasts (but not HFL1) showed increased expression of this gene under conditions of HRV infection (361% for HRV-16 and 338% for HRV-2, p < 0.05) with relaxin. The gene discussed is RXFP1; the disease is infection.
