OAS2 and Bovine mastitis: Our data suggest that genes TLR4, NOD2, CXCL8, and OAS2 are key components involved in the host immune response to bovine mastitis and that the lncRNAs MSTRG25101.2, MSTRG.56327.1, and MSTRG.18968.1 adjacent to the SCC QTL and SCS QTL may potentially regulate expression of these candidate genes.
