Brown Adipocyte and Splenocyte Co-Culture Maintains Regulatory T Cell Subset in Intermittent Hypobaric Conditions

EBF2 determines and maintains brown adipocyte identity.

The master transcription factor Pparγ regulates the general differentiation program of both brown and white adipocytes. However, it has been unclear whether Pparγ also controls fat lineage-specific characteristics. Here, we show that early B cell factor-2 (Ebf2) regulates Pparγ binding activity to determine brown versus white adipocyte identity. The Ebf DNA-binding motif was highly enriched wit...

Regulatory circuits controlling white versus brown adipocyte differentiation.

Adipose tissue is a major endocrine organ that exerts a profound influence on whole-body homoeostasis. Two types of adipose tissue exist in mammals: WAT (white adipose tissue) and BAT (brown adipose tissue). WAT stores energy and is the largest energy reserve in mammals, whereas BAT, expressing UCP1 (uncoupling protein 1), can dissipate energy through adaptive thermogenesis. In rodents, ample e...

Regulatory T Cell Subtypes and TGF-β1 Gene Expression in Chronic Allograft Dysfunction

Background: Regulatory T cells have been suggested to have a protective role against acute rejection in allograft recipients. However, there is little information available about their contribution to chronic rejection process. The role of transforming growth factor-beta 1 (TGF- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. Objectives: To eva...

Circulating and Tumor-Infiltrating Foxp3+ Regulatory T Cell Subset in Chinese Patients with Extranodal NK/T Cell Lymphoma

Foxp3⁺ regulatory T lymphocytes (Tregs) usually act as an immune suppressor and correlate with poorer survival in malignancies. This study aims to investigate the distribution and characterization of Foxp3(+) subset in peripheral blood mononuclear cells (PBMCs) and tumor tissues from extranodal NK/T cell lymphoma (ENKTL). Our study showed the percentage of Foxp3⁺ subset from PBMC was significan...
