“…TLRs recognise the conserved microbial patterns such as flagellin, LPS, peptidoglycan in an efficient and non self reactive manner to initiate pro inflammatory cytokines. Role of TLR in the immunomodulation has been demonstrated and at least 10 TLRs have been identified in chickens, including TLR1A, 1B, 2A, 2B, 3, 4, 5, 7, 15 and 21 (Barjesteh et al, 2013;St Paul et al, 2013). Sunder et al (2014b) studied that supplementation of Noni and Kalmegh influenced the expression levels of TLR-2, TLR-3, TLR-4, TLR-5, TLR-15 and TLR-21 significantly (P<0.05).…”
