Gut Microbiota Regulates Systemic Inflammatory Response and Compensatory Anti‐Inflammatory Response Syndromes by Targeting PF4+ Macrophages in Acute Pancreatitis

Advanced Science, EarlyView.
ABSTRACT Acute pancreatitis (AP) begins with pancreatic local inflammation, leading to the onset of systemic inflammatory response syndrome (SIRS), followed by compensatory anti‐inflammatory response syndrome (CARS), which causes immune paralysis and higher mortality rate.

Genome‐Wide CRISPR Screen Identifies a microRNA Orchestrating Pleiotropic Resistance to Targeted Therapy and T Cell Immunity in Melanoma

Advanced Science, EarlyView.
A genome‐wide microRNA CRISPR screen identifies miR‐18a as a master regulator of cross‐resistance in melanoma. Loss of miR‐18a activates the AJUBA–YAP/Hippo axis to confer BRAFi resistance and enhances THBS1–CD47 interaction to impair CD8+ T cell immunity. hnRNP A1 is identified as an upstream regulator of miR‐18a processing.

Molecular evaluation of the anticancer potential of 1,3,4-oxadiazole-2-thiones derivative and its synergetic action with Nigella sativa seed extract (Thymoquinone) in experimentally induced Murine Lung Cancer Cell Line Model. [PDF]

Journal of Medical and Life Science
Lung cancer persistently poses as a primary factor in cancer-linked deaths globally, necessitating novel treatment strategies. This investigation appraises the anti-tumor potential of Thymoquinone (TQ) and 1,3,4-oxadiazole derivatives independently and ...

CD4 testing after initiation of antiretroviral therapy: Analysis of routine data from the South African HIV programme

Southern African Journal of HIV Medicine, 2020
Background: People living with HIV (PLHIV) who have low CD4 counts require advanced clinical care (ACC) to minimise morbidity and mortality risk. These patients include immunological non-responders (INRs) with low CD4 counts despite a suppressed viral ...

PRMT1‐Mediated LDHA Methylation Drives STAT3 Lactylation to Orchestrate Intestinal Inflammation and Tumorigenesis

Advanced Science, EarlyView.
This study identifies an immunometabolic axis wherein SAM‐driven PRMT1 methylates LDHA, enhancing its activity. The resultant lactate induces STAT3 K709 lactylation, which stabilizes an active conformation to promote STAT3 phosphorylation and IL‐10 expression.

Occult Hepatitis B Virus Infection in Egyptian HIV-Infected Patients with Isolated Anti-HBc

Journal of High Institute of Public Health, 2019
Background : Occult hepatitis B infection (OBI), defined as the presence of hepatitis B virus (HBV) DNA in liver or serum despite the absence of detectable hepatitis B surface antigen (HBsAg) is a frequent contaminant with human immunodeficiency virus ...

RNA Helicase DDX21 Controls CD4+ T Cell Proliferation and Promotes Inflammatory Bowel Disease via Translational Control

Advanced Science, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD) is characterized by dysregulated T cell responses. RNA helicases, including DExD‐box helicase 21 (DDX21), are pivotal in RNA metabolism, but their role in T cell‐mediated pathology during IBD remains unclear. Here, we demonstrate that DDX21 expression in CD4+ T cells correlates with cell cycle and translation ...

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe

Advanced Science, EarlyView.
This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

Relationships between 2H4 (CD45RA) and UCHL1 (CD45RO) expression by normal blood CD4+CD8−, CD4−CD8+, CD4−CD8dim+, CD3+ CD4−CD8− and CD3−CD4−CD8− lymphocytes

Clinical and Experimental Immunology, 1990
SUMMARYWe characterized and established relationships between the expression of membrane 2H4 (CD45R A) and UCHL1 (CD45RO) by enriched lymphocyte fractions prepared by selective immunomagnetic depletion of monoclonal antibody-defined populations. Cell fractions analysed in this study could be divided into two broad groups according to the presence (CD.3+

A Radioresistant‐Tumor‐Targeted Nanoparticle for X‐Ray‐Controlled Nitric Oxide Release to Potentiate Radiotherapy

Advanced Science, EarlyView.
The PBTN targets GRP78 and, upon X‐ray irradiation, generates ONOO− to induce immunogenic cell death, thereby activating CD8+ T cells and establishing a systemic antitumor immune response. ABSTRACT Nitric oxide (NO) treated radioresistant tumors by relieving hypoxia and blocking DNA repair, but its nonselective toxicity has precluded therapeutic use ...
