Table 21. Summary Review of MAP-Induced TLR and MHC Responses.

Infection Model Expression level Reference
Blood samples from four MAP exposed and four unexposed cattle Unconfirmed association between MAP exposure and in-vivo MHC gene modulation [83]
In silico analysis, for a population-based genetic association of a Spanish Holstein-Friesian sample 3 tightly linked SNP in TLR4 were found to be associated with susceptibility to MAP infection [84]
Early paucibacillary MAP infection compared to multibacillary MAP infection in sheep Lower expression levels of most TLRs in paucibacillary group than the multibacillary group [85]
MAP infected monocyte-derived dendritic cells Unable to present antigen via MHC class II [82]
In vitro infection of Chinese Hamster Ovary (CHO) cells with MAP Low TLR4 [81]
Peripheral blood derived macrophages from juvenile sheep Down-regulation of MHC class I and II [80]
Bovine macrophages infection (in-vitro) with MAP Down-regulation of MHC class I and class II molecules [86]
Intestinal macrophages in clinically infected sheep compared with normal tissues Lower expression of MHC class II [79]
