Understanding dietary carbohydrates in black soldier fly larvae treatment of organic waste in the circular economy.

Black soldier fly larvae (BSFL) treatment is promising for organic waste valorisation in the circular economy; however, waste variability impacts the process performance and quality of produced larvae. Specifically, variation in the carbohydrate profile of treated wastes has been suggested to have a significant impact on BSFL treatment performance and quality of produced larvae, with particular carbohydrates either positively or negatively influencing these variables. This study examines the hypothesis that the types of carbohydrates within the substrate can have significant influence on larval survival, waste reduction, bioconversion, and waste conversion efficiency, as well as the crude lipid content and fatty acid profiles of the produced larvae.

Early-onset age-related changes in dendritic cell subsets can impair antigen-specific T helper 1 (Th1) CD4 T cell priming.

Decline in CD4 T cell immune responses is associated with aging. Although a number of immunological defects have been identified in elderly mice (>18 months old), a key early-onset immune defect at middle age could be a driver or contributor to defective CD4 T cell responses. Our studies demonstrate that age-related alterations in DC subsets within the priming environment of middle-aged mice (12 months old) correlate with and can directly contribute to decreases in antigen-specific CD4 T cell Th1 differentiation, which measured by T-bet and IFN-γ expression, was decreased significantly in T cells following VSV infection or s.

Defects in the peripheral taste structure and function in the MRL/lpr mouse model of autoimmune disease.

While our understanding of the molecular and cellular aspects of taste reception and signaling continues to improve, the aberrations in these processes that lead to taste dysfunction remain largely unexplored. Abnormalities in taste can develop in a variety of diseases, including infections and autoimmune disorders. In this study, we used a mouse model of autoimmune disease to investigate the underlying mechanisms of taste disorders.
