Immunopharmacology Comments
Evidence suggests that PKN1 plays a role in modulation of the NF-κB signalling pathway. Specifically, in Salmonella infection, PKN1 is hijacked by a bacterial effector protein which results in inhibition of NF-κB-dependent gene expression (i.e. inhibition of production of the proinflammatory cytokines that would normally effect bacterial destruction and removal) [4]. PKN1 also plays a role in germinal center formation, by negatively regulating Akt kinase downstream of the B cell receptor [11], and SNPs in PKN1 (and several other genes) are suggestively associated with the presence of ectopic germinal center-like structures in the minor salivary glands of some patients (25%) with the autoimmune disease, primary Sjögren's syndrome [9].
