Intestinal TLR4 deletion exacerbates acute pancreatitis through gut microbiota dysbiosis and Paneth cells deficiency.

Toll-like receptor 4 (TLR4) has been identified as a potentially promising therapeutic target in acute pancreatitis (AP). However, the role of intestinal TLR4 in AP and AP-associated gut injury remains unclear. This study aimed to explore the relationship between intestinal TLR4 and gut microbiota during AP.

Loss and Gain in the Evolution of the Serovar Gallinarum Biovar Pullorum Genome.

subspecies serovar Gallinarum biovar Pullorum ( Pullorum) is the etiological agent of pullorum disease, causing white diarrhea with high mortality in chickens. There are many unsolved issues surrounding the epidemiology of Pullorum, including its origin and transmission history as well as the discordance between its phenotypic heterogeneity and genetic monomorphism. In this paper, we report the results of whole-genome sequencing of a panel of 97 Pullorum strains isolated between 1962 and 2014 from four countries across three continents.

Differential Effects of Mycobacterium bovis BCG on Macrophages and Dendritic Cells from Murine Spleen.

Macrophages (MΦ) and dendritic cells (DCs) are both pivotal antigen presenting cells capable of inducing specific cellular responses to inhaled mycobacteria, and thus, they may be important in the initiation of early immune responses to mycobacterial infection. In this study, we evaluated and compared the roles of murine splenic DCs and MΦs in immunity against Mycobacterium bovis Bacillus Calmette-Guérin (M.bovis BCG).
