At early time points MAPK-p38 phosphorylation was greater in MAP-infected bovine monocytes than in Maa-infected monocytes.

Although the mechanism is complex, several studies have incriminated signaling through TLR2 receptors with subsequent activation of the MAPK pathway p38 (MAPKp38) and overproduction of IL-10 in the survival of pathogenic mycobacterial organisms.
In the present study, we compared the response of bovine monocytes with infection by Mycobacterium avium subspecies paratuberculosis (MAP), the cause of paratuberculosis in ruminants, with the closely related organism M. avium subspecies avium (Maa), which usually does not cause disease in ruminants.

TGF-beta1 is the major contributor to the activation of extracellular signal-related kinase (ERK), p38, and c-Jun N-terminal kinase (JNK), leading to the activation of AP-1 and NF-kappaB on the IL-8 promoter and initiation of IL-8 mRNA and protein release, thereby promoting osteoclastogenesis.
