Regulatory T cells (Tregs) has been shown to be involved in the induction of transplantation tolerance in numerous models. Our previous work demonstrated that METTL14 loss impaired Treg function and hindered the establishment of transplantation tolerance. However, the underlying mechanisms remain unclear.

Nutritional status is a determining factor for growth during development and homeostatic maintenance in adulthood. In the context of muscle, growth hormone (GH) coordinates growth with nutritional status; however, the detailed mechanisms remain to be fully elucidated. Here, we show that the transcriptional repressor B cell lymphoma 6 (BCL6) maintains muscle mass by sustaining GH action.

Background: Calcific aortic valve disease is the pathological remodeling of valve leaflets. The initial steps in valve leaflet osteogenic reprogramming are not fully understood. As TERT (telomerase reverse transcriptase) overexpression primes mesenchymal stem cells to differentiate into osteoblasts, we investigated whether TERT contributes to the osteogenic reprogramming of valve interstitial cells.

Introduction/aims: Tofacitinib, a first-generation Janus kinase (JAK) 1/3 inhibitor, is commonly used for treating ulcerative colitis and rheumatoid arthritis. However, its role in myasthenia gravis (MG) remains unclear. This study aimed to evaluate the immunomodulatory effects of tofacitinib on experimental autoimmune myasthenia gravis (EAMG) and peripheral blood mononuclear cells (PBMCs) from patients with MG.

Epidermal growth factor receptor (EGFR) plays an important role in the regulation of cell proliferation and migration [1]. It forms a homodimer or heterodimer with other ErbB receptor family members to activate downstream signaling. Emerging evidence indicates that the EGFR activity and downstream signaling are regulated by other proteins except its family members during tumorigenesis.
