Oncolytic Virus‐Engineered Extracellular Vesicles Rewire Glioblastoma Immunity

Journal of Extracellular Vesicles, Volume 15, Issue 10, October 2026.
ABSTRACT Immunotherapy with oncolytic Herpes simplex virus type 1 (oHSV‐1) shows promise for glioblastoma; however, clinical benefit remains uncommon due to tumour‐ and host‐mediated immunosuppression, which limits immune targeting of residual glioblastoma stem‐like cells (GSCs). To address this barrier, extracellular vesicles (EVs) harvested from oHSV‐

Cytomegalovirus in Bronchoalveolar Lavage Fluid: A Predictor of Outcome in Immunocompromised Patients

Journal of Medical Virology, Volume 98, Issue 10, October 2026.
ABSTRACT Cytomegalovirus (CMV) is a prevalent herpesvirus that remains typically asymptomatic in immunocompetent individuals but can cause severe, potentially life‐threatening disease in immunocompromised patients. This study assessed the impact of CMV‐associated lower respiratory tract infections (LRTIs), diagnosed by polymerase chain reaction (PCR ...

Thymic Involution and Function in People With HIV and General Population Controls: A Cross‐Sectional Analysis From Two Danish Cohort Studies

Aging Cell, Volume 25, Issue 10, October 2026.
Thymic involution, the age‐related replacement of thymic soft tissue by fat, has been linked to immunosenescence and chronic inflammation. Whether HIV infection affects thymic involution remains unclear. We found that people with HIV on long‐term antiretroviral therapy had more thymic tissue than controls, indicating less thymic involution. More thymic

Genital Tract and Circulating CD8+ T Cell Phenotypes Vary Across the Menstrual Cycle

American Journal of Reproductive Immunology, Volume 96, Issue 4, October 2026.
ABSTRACT Problem The menstrual cycle consists of two main phases: the follicular phase, characterized by rising estradiol and low progesterone, and the luteal phase, marked by elevated progesterone following ovulation. Changes in sex hormones have profound physiological effects, yet their impact on immunity remains poorly understood.
