POLE mutations in endometrial carcinoma: Clinical and genomic landscape from a large prospective single-center cohort.
Cancer
February 2025
Departmental Unit of Molecular and Genomic Diagnostics, Genomics Core Facility, G-STeP, Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy.
Background: To date, 11 DNA polymerase epsilon (POLE) pathogenic variants have been declared "hotspot" mutations. Patients with endometrial cancer (EC) characterized by POLE hotspot mutations (POLEmut) have exceptional survival outcomes. Whereas international guidelines encourage deescalation of adjuvant treatment in early-stage POLEmut EC, data regarding safety in POLEmut patients with unfavorable characteristics are still under investigation.

February 2025
IRCCS Istituto delle Scienze Neurologiche di Bologna, Department of Neurology and Stroke Center, Maggiore Hospital, Bologna, Italy.
Background: To investigate the relevance of hyperperfusion on computerised perfusion imaging (CTP) in the emergency setting in people with non-convulsive status epilepticus (NCSE) and previous stroke, to derive relevant aspects on the epileptogenic focus and the network recruited for NCSE propagation.
Methods: We enrolled consecutive adult patients with acute-onset NCSE and a previous stroke at a single institution undergoing CTP and EEG during symptoms. All patients underwent standard imaging including CT, CTP, CT angiograms and standard EEG within 30 min from hospital arrival.

J Biol Chem
January 2025
State Key Laboratory of Pharmaceutical Biotechnology, Department of Biochemistry, School of Life Sciences, Nanjing University, Nanjing, 210023, China. Electronic address:
Given the pivotal role of the Eph-Ephrin signaling pathway in tumor progression, agonists or antagonists targeting Eph/Ephrin have emerged as promising anticancer strategies. However, the implications of glycosylation modifications within Eph/Ephrin and their targeted protein therapeutics remain elusive. Here, we identify that N-glycosylation within the receptor-binding domain (RBD) of ephrin B1 (EFNB1) is indispensable for its functional repertoire.

Tuberculosis (Edinb)
January 2025
Emory Vaccine Center, Emory University, Atlanta, GA, USA; Emory National Primate Research Center, Atlanta, GA, USA; Department of Microbiology and Immunology, Emory University School of Medicine, Atlanta, GA, USA. Electronic address:
Infection with HIV is associated with dysregulated CD4 T cell responses to Mycobacterium tuberculosis (Mtb) and increased risk of developing tuberculosis. Mtb-specific CD4 T cells in people with HIV have diminished Th1 cytokine production capacity, thus we utilized a flow cytometry-based assay to measure CD40L expression by Mtb-specific CD4 T cells in a cytokine-independent manner. We evaluated the frequency and phenotype of Mtb-specific CD4 responses in Kenyan adults with latent Mtb infection and found that the majority of Mtb-specific CD4 T cells expressed CD40L in the absence of IFN-γ, regardless of HIV infection status.
