Biological and chemical characterization of new isolated halophilic microorganisms from saltern ponds of Trapani, Sicily
2021
Abstract Halophilic microorganisms inhabiting hypersaline environments such as salt lakes, Dead Sea, or salt evaporation ponds, have acquired specific cell adaptation to grow within stressful conditions. In this study, we isolated heterotrophic and autotrophic microorganisms from several saltern ponds located at the Natural Reserve “Saline di Trapani e Paceco”, Sicily, Italy. The aim of the study was to investigate the biotechnological potential of new microbial strains from saltern ponds, by capturing their biological and chemical diversity. After the isolation and identification of the sampled strains, their growth capacity was determined under low and high salinity conditions. The metabo…
Targeting cellular fatty acid synthesis limits T helper and innate lymphoid cell function during intestinal inflammation and infection
2019
CD4+ T cells contribute critically to a protective immune response during intestinal infections, but have also been implicated in the aggravation of intestinal inflammatory pathology. Previous studies suggested that T helper type (Th)1 and Th17 cells depend on de novo fatty acid (FA) synthesis for their development and effector function. Here, we report that T-cell-specific targeting of the enzyme acetyl-CoA carboxylase 1 (ACC1), a major checkpoint controlling FA synthesis, impaired intestinal Th1 and Th17 responses by limiting CD4+ T-cell expansion and infiltration into the lamina propria in murine models of colitis and infection-associated intestinal inflammation. Importantly, pharmacolog…
