Chronic MR As patients evolve from acute to chronic MR, the LV dilates and changes from a small hyperkinetic chamber in acute MR to a large compliant chamber ( atrial functional MR is less well-studied, and likely related to left atrial enlargement, displacement of posterior annulus onto the crest of the LV, close apposition of posterior mitral leaflet to the LV wall, reduction in posterior leaflet area for coaptation, and counterclockwise torque of the anterior mitral annulus causing tethering of the anterior mitral leaflet with leaflet tenting ( Disease Prognosis and Natural History Severe untreated MR has a fairly poor prognosis irrespective of etiology
ludwiggi protects against DSS-induced colitis by enhancing the choline/7nAChR-mediated dendritic cell immune tolerance, leading to increased Foxp3 + Treg differentiation ( + dendritic cells from Enterobacter ludwiggi -treated mice exhibited higher expression of tolerogenic markers Tgfb1, Tgfb2, Aldh1a2 , and Pdl1 , and co-culture with nave CD4 + T cells enhances Treg conversion ( Enterobacter ludwiggi exhibited reduced colitis severity and expanded Treg populations in the mesenteric lymph nodes and spleen, highlighting cholines role in shaping gut-immune interactions
