Abstract
GPR15 functions as a cellular co-receptor for some isolates of HIV-1, HIV-2, and SIV through interactions with several viral envelope proteins. The objective of this study was to investigate the expression of orphan receptor GPR15/BOB in the serum of SLE patients and non-SLE healthy people. GPR15/BOB expression was analysed by flow cytometry while, GPR15/BOB messenger RNA was examined in peripheral blood monocytes by RT-PCR. GPR15/BOB mRNA was detected in all periphral blood of SLE patients examined. Further, a significant increase in GPR15/BOB expression as measured by mean fluorescence intensity was observed on SLE PB neutrophils compared to these cell populations from healthy donors. We concluded that GPR15/BOB is expressed in monocytes and neutrophils in peripheral blood, and expression is up-regulated in SLE patients compared to controls. GPR15/BOB may play a role in SLE pathogenesis.
