The paper presents the results of a study of spontaneous and stimulated production of TNF-alpha, INF-gamma, INF-alpha, IL-2 by peripheral mononuclear leukocytes in patients with disseminated destructive drug-resistant pulmonary tuberculosis. It also shows marked changes in the levels the studied cytokines in relation to the type of a stimulant (lipopolysaccharide, phytohemagglutinin, tuberculin) and during antituberculous chemotherapy.

Background Aims: Bulevirtide (BLV) is a novel and the only approved treatment option for patients with chronic hepatitis D (CHD). BLV alleviates liver inflammation already early during treatment when only minor HDV RNA changes are observed. We hypothesized that BLV-treatment may influence immune cells in CHD patients and performed a high-resolution analysis of natural killer (NK) cells before and during BLV-therapy.

Downregulation of MerTK in circulating T cells of patients with non-proliferative diabetic retinopathy.

Front Endocrinol (Lausanne)

January 2025

Department of Ophthalmology, The Second Affiliated Hospital, School of Medicine, South China University of Technology, Guangzhou, China.

Objective: To explore the differential gene expression in peripheral blood immune cells of individuals with type 2 diabetes mellitus (DM), comparing those with and without non-proliferative diabetic retinopathy (NPDR).

Methods: From a pool of 126 potential participants, 60 were selected for detailed analysis. This group included 12 healthy donors (HDs), 22 individuals with DM, and 26 with NPDR.

Increased Rate of Unique Mitochondrial DNA Deletion Breakpoints in Young Adults With Early-Life Stress.

Biol Psychiatry Glob Open Sci

March 2025

Initiative on Stress, Trauma, and Resilience, Department of Psychiatry and Human Behavior, Warren Alpert Medical School, Brown University, Providence, Rhode Island.

Background: Mounting evidence suggests that mitochondria respond to psychosocial stress. Recent studies suggest mitochondrial DNA (mtDNA) deletions may be increased in some psychiatric disorders, but no studies have examined early-life stress (ELS) and mtDNA deletions. In this study, we assessed mtDNA deletions in peripheral blood mononuclear cells of medically healthy young adults with and without ELS.

Introduction: An effective vaccination policy must be implemented to prevent foot-and-mouth disease (FMD). However, the currently used vaccines for FMD have several limitations, including induction of humoral rather than cellular immune responses.

Methods: To overcome these shortcomings, we assessed the efficacy of levamisole, a small-molecule immunomodulator, as an adjuvant for the FMD vaccine.

Ras Guanine Nucleotide-Releasing Protein-4 Inhibits Erythropoietin Production in Diabetic Mice with Kidney Disease by Degrading HIF2A.

Diabetes Metab J

January 2025

NHC Key Laboratory of Hormones and Development, Chu Hsien-I Memorial Hospital and Tianjin Institute of Endocrinology, Tianjin Medical University, Tianjin, China.

Background: In acute and chronic renal inflammatory diseases, the activation of inflammatory cells is involved in the defect of erythropoietin (EPO) production. Ras guanine nucleotide-releasing protein-4 (RasGRP4) promotes renal inflammatory injury in type 2 diabetes mellitus (T2DM). Our study aimed to investigate the role and mechanism of RasGRP4 in the production of renal EPO in diabetes.
