Role of transforming growth factor-β1 in regulating adipocyte progenitors.

Adipose tissue (AT) metabolism involves coordinating various cells and cellular processes to regulate energy storage, release, and overall metabolic homeostasis. Therein, macrophage and its cytokine are important in controlling tissue homeostasis. Among cytokines, the role of transforming growth factor-β1 (Tgf-β1), a cytokine abundantly expressed in CD206 M2-like macrophage and correlated with the expansion of AT and fibrosis, in AT metabolism, remains unknown.

Clinical characteristics affecting weight loss in an East Asian population receiving semaglutide: A STEP 6 subgroup analysis.

Objective: To explore the effects of semaglutide versus placebo on body weight (BW) by subgroups of baseline characteristics.

Methods: In STEP 6, Japanese and Korean adults with overweight or obesity were randomized to subcutaneous semaglutide 2.4 mg, semaglutide 1.

Identification of herbal drug extracts that promote growth of in high-fat diet fed mice.

Unlabelled: Disruption of the gut microbiota causes metabolic dysfunction, and intervention in the gut microbiota has the potential to improve host glucose metabolism. is an intestinal bacterium involved in anti-obesity and insulin resistance. Developing interventions to increase would be useful for new treatment strategies.

Comparison of the efficacy of first‑/second‑generation EGFR‑tyrosine kinase inhibitors and osimertinib for EGFR‑mutant lung cancer with negative or low PD‑L1 expression.

In epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) with negative or low programmed death ligand-1 (PD-L1) expression, the acquisition rate of the T790M mutation is higher after treatment with first-/second-generation EGFR-tyrosine kinase inhibitors (TKIs) and the progression-free survival (PFS) is longer in patients treated with osimertinib. The present study compared the clinical course after the initiation of each EGFR-TKI monotherapy in patients with EGFR-mutant NSCLC with negative or low PD-L1 expression. Data of patients with EGFR-mutant NSCLC with negative or low PD-L1 expression who were treated with EGFR-TKI monotherapy were retrieved and retrospectively analyzed.

History and future perspectives of adipose tissue macrophage biology.

Macrophages contribute to adipose tissue homeostasis; however, they are also thought to be responsible for insulin resistance in obesity. Macrophages, which were oversimplified in past methodologies, have become rather difficult to understand comprehensively as recent developments in research methodology have revealed their diversity. This review highlights recent studies on adipose tissue macrophages, identifies controversial issues that need to be resolved and proposes a scenario for further development of adipose tissue macrophage biology.
