The expression of gingival epithelial junctions in response to subgingival biofilms.

abstract：:Many studies have found that abnormalities in the proportion and differentiation of CD4+ T cells (Th cells) are closely related to the pathogenesis of viral myocarditis (VMC). Our previous research indicates that the cholinergic anti-inflammatory pathway (CAP) attenuates the inflammatory response of VMC and downregula...
