Furthermore, CXCL13 levels correlated with sCD44 levels in the AIDS-NHL group (R = 0.31, P = .04), but not in the AIDS control group (R = 0.07; P = .7, data not shown); we previously showed that sCD44 levels are elevated prior to AIDS-NHL development [40]. The gene discussed is CXCL13; the disease is non-Hodgkin lymphoma.
