Article Abstract

Microglia/macrophage activation plays an essential role in Ischemic stroke (IS). Nuclear receptor corepressor 1 (NCoR1) has been identified as a vital regulator in macrophages. The present study aims to explore the functions of macrophage NCoR1 in IS. Macrophage NCoR1 knockout (MNKO) mice and littermate control mice were subjected to middle cerebral artery occlusion (MCAO). Our data showed that macrophage NCoR1 deficiency significantly reduced the infarct size and infarct volume as well as brain edema after MCAO. Additionally, MNKO induced less microglia/macrophage infiltration and activation, neuroinflammation, apoptosis of neuronal cells, and BBB disruption in brains after IS. Mechanistic studies revealed that NCoR1 interacted with LXRβ in microglia and MNKO impaired the activation of the Nuclear factor-κB signaling pathway in brains after IS. Our data demonstrated that macrophage NCoR1 deficiency inhibited microglia/macrophage activation and protected against IS. Targeting NCoR1 in microglia/macrophage may be a potential approach for IS treatment.

Purpose: To explore the role of the peroxisome proliferator-activated receptor (PPAR) signaling pathway in chronic obstructive pulmonary disease (COPD) and identify potential biomarkers and therapeutic targets, given that COPD is a major global health burden and the specific molecular mechanisms of the PPAR pathway in COPD are not fully understood.

Patients And Methods: Gene expression data from the GEO database were analyzed to identify key genes and immune cells related to COPD. Peripheral blood samples were collected from COPD patients and healthy controls.

Introduction: Systemic Lupus Erythematosus (SLE) impacts the central nervous system (CNS), leading to severe neurological and psychiatric manifestations known as neuropsychiatric lupus (NPSLE). The complexity and heterogeneity of clinical presentations of NPSLE impede direct investigation of disease etiology in patients. The limitations of existing mouse models developed for NPSLE obstruct a comprehensive understanding of this disease.

Macrophage polarization plays an important role in asthma. Nuclear receptor corepressor 1 (NCOR1) plays an important role in metabolic and cardiovascular diseases by regulating the function of macrophages. The aim of this research was to examine the role and mechanism of macrophage NCOR1 in the development of asthma.

Mycobacterium tuberculosis (Mtb) defends host-mediated killing by repressing the autophagolysosome machinery. For the first time, we report NCoR1 co-repressor as a crucial host factor, controlling Mtb growth in myeloid cells by regulating both autophagosome maturation and lysosome biogenesis. We found that the dynamic expression of NCoR1 is compromised in human peripheral blood mononuclear cells (PBMCs) during active Mtb infection, which is rescued upon prolonged anti-mycobacterial therapy.

Background: Combination therapy with radioembolization (yttrium-90)-resin microspheres) followed by nivolumab has shown a promising response rate of 30.6% in a Phase II trial (CA209-678) for advanced hepatocellular carcinoma (HCC); however, the response mechanisms and relevant biomarkers remain unknown.

Methods: By collecting both pretreatment and on-treatment samples, we performed multimodal profiling of tissue and blood samples and investigated molecular changes associated with favorable responses in 33 patients from the trial.
