AI Article Synopsis

  • Obesity is a leading cause of insulin resistance, contributing to the rising rates of type 2 diabetes mellitus (T2DM) due to the associated chronic inflammation.
  • Recent studies highlight how obesity-induced inflammation affects key metabolic tissues, particularly emphasizing the impacts of adipose tissue hypoxia and exosomes from macrophages.
  • The review also explores current and emerging therapies aimed at modifying the immune response to address these metabolic issues.

Article Abstract

Obesity is the most common cause of insulin resistance, and the current obesity epidemic is driving a parallel rise in the incidence of T2DM. It is now widely recognized that chronic, subacute tissue inflammation is a major etiologic component of the pathogenesis of insulin resistance and metabolic dysfunction in obesity. Here, we summarize recent advances in our understanding of immunometabolism. We discuss the characteristics of chronic inflammation in the major metabolic tissues and how obesity triggers these events, including a focus on the role of adipose tissue hypoxia and macrophage-derived exosomes. Last, we also review current and potential new therapeutic strategies based on immunomodulation.

Juice and decoction of leaves of Suaeda fruticosa, a halophytic medicinal plant of Cholistan desert, is traditionally used to treat rheumatism. The current study was carried out to probe into in vivo anti-nociceptive, anti-inflammatory, and anti-arthritic potential of ethanolic extract of the whole plant of S. fruticosa (Et-SF) and its bioactive molecules.

Purpose Of Review: The canonical pathogenesis of spondyloarthritis (SpA) involves inflammation driven by HLA-B27, type 3 immunity, and gut microbial dysregulation. This review based on information presented at the SPARTAN meeting highlights studies on the pathogenesis of SpA from the past year, focusing on emerging mechanisms such as the roles of microbe-derived metabolites, microRNAs (miRNAs) and cytokines in plasma exosomes, specific T cell subsets, and neutrophils.

Recent Findings: The induction of arthritis in a preclinical model through microbiota-driven alterations in tryptophan catabolism provides new insights as to how intestinal dysbiosis may activate disease via the gut-joint axis.

In clinical mastitis of dairy cows, the abnormal accumulation of apoptotic cells (ACs) and subsequent secondary necrosis and inflammation pose significant concerns, with macrophage-mediated efferocytosis, crucial for ACs clearance, remaining unexplored in this context. In nonruminants, MER proto-oncogene tyrosine kinase (MERTK) receptors are essential for efferocytosis and A Disintegrin and Metalloproteinase 17 (ADAM17) is thought to play a role in regulating MERTK integrity. This study aimed to delineate the in situ role of efferocytosis in clinical mastitis, with a particular focus on the interaction between MERTK and ADAM17 in bovine macrophages.

Introduction: ICAM-1 is an adhesion molecule expressed on the endothelial cells and is involved in regulating leukocyte recruitment to the site of inflammation. Elevated ICAM-1 mRNA expression was found in the serum of mothers with chorioamnionitis. This study aimed to determine the expression of ICAM-1 in the placenta and umbilical cord of pregnancy with chorioamnionitis, and its association with adverse neonatal outcome.
