Summary: The study found that BPA can induce inflammatory response in the lungs, possibly through the TLR4/NF-kappa B signaling pathway and mTOR-mediated autophagy. Inhibition of autophagy can weaken the inflammatory response.

Summary: This study demonstrates that chronic exposure to BPA can lead to inflammatory infiltration, tubular injury, and fibrosis in the kidneys of healthy mice, and exacerbation of renal lesions in SNX mice. BPA also modulates the autophagy process and redox protective mechanisms in the kidneys, suggesting potential harmful effects of BPA in the kidneys.

Summary: This study reveals the important role of TM9SF1 in LPS-induced acute lung injury (ALI). Knocking out TM9SF1 significantly alleviates LPS-induced ALI by regulating autophagy. This discovery may provide novel targets for the treatment of ALI.

Summary: Tetrabromobisphenol A (TBBPA), a non-degradable environmental pollutant, is released into the air during the production, use, and recycling of plastic products. Respiratory exposure is the main route of TBBPA inhalation. However, research on the respiratory system damage caused by TBBPA is limited. This study aimed to investigate the mechanism of TBBPA toxicity to the lungs. Results showed that exposure to TBBPA led to inflammatory cell infiltration and tissue structure damage in the lungs of mice. Increased levels of ROS and MDA, as well as inhibition of T-AOC, GSH-Px, CAT, and SOD activities, were observed in lung tissue with TBBPA exposure. The expression of autophagy-related factors Beclin-1, P62, LC3-II, ATG5, and ATG7 decreased. Activation of the NF kappa B/TNF-alpha pathway indicated inflammation. Increased expression of Bax, caspase3, caspase7, caspase 9, decreased expression of Bcl-2, and activation of the apoptosis pathway were observed. The autophagy inducer rapamycin could reverse the adverse effects of inflammation and apoptosis. Together, TBBPA inhibits autophagy-induced pneumonia and apoptosis by overproducing ROS.

Summary: Autophagy is a highly conserved process that maintains cell stability and function, and helps resist pathogen invasion. It plays a role in various diseases, including lung diseases like acute lung injury (ALI). Traditional Chinese medicine has been used to regulate autophagy and improve ALI symptoms. This paper introduces the molecular mechanism and common pathways of autophagy regulation, as well as the relationship between autophagy and ALI, and summarizes the active ingredients of traditional Chinese medicine that improve ALI symptoms by regulating autophagy.

Summary: This study investigates the effects of BPA on macrophages and its mechanism of action. The results show that BPA decreases cell viability and disrupts macrophage function by inhibiting autophagy and inducing apoptosis. Activation of autophagy and inhibition of apoptosis can ameliorate the damage caused by BPA on macrophages.

Summary: The study demonstrated that dexmedetomidine reverses lung injury in toxic shock rats by inhibiting inflammation and autophagy. Dexmedetomidine treatment significantly reduced the levels of inflammatory cytokines and decreased the expression of autophagy-related proteins, resulting in an attenuation of lung injury in rats with toxic shock.

Summary: Autophagy is a crucial self-degradative process in cells that plays a key role in cellular renovation, physiology, and homeostasis. It can be triggered by factors such as starvation, pathogens, and stress, and is important in immune response regulation. Dysregulation of autophagy processes, either impaired or overactive, can contribute to the pathogenesis of various diseases, including infections and cancer.

Summary: Riffelmacher et al. show that immunization with a live vaccine strain leads to the expansion of two memory-like mucosal-associated invariant T cell lineages with distinct metabolic needs, effector programmes and protective capacities. CD127(+) MAIT cells engage in an energetic, mitochondrial metabolic programme and rely on high fatty acid uptake and mitochondrial oxidation, while Klrg1(+) MAIT cells depend on Hif1a-driven glycolysis and have dormant but ready-to-respond mitochondria. These metabolic dependencies may enable tuning of memory-like MAIT cell responses for vaccination and immunotherapies.
