MR is one of the putative SRLV receptors and, although MR transcripts have been found in vitro in sheep monocytes/macrophages and synovial membrane fibroblasts [10], the levels of MR transcripts in SRLV target tissues from natural clinical infections have not been assessed so far and it is unknown if MR could play a role in SRLV pathogenesis. Here, NR3C2 is linked to infection.
