Objective: A pathogenetic role of CD8+ T lymphocytes in radiographic axial spondyloarthritis (r-axSpA) and other spondyloarthritis (SpA) is sustained by genome-wide association studies (GWAS) and by the expansion of public T cell clonotypes in the target tissues. This study investigates the migration of CD8+ T cells, along with their phenotype and functions in patients with r-axSpA and psoriatic arthritis (PsA).
Methods: Peripheral blood CD8+ and CD4+ T cells were isolated from r-axSpA (n= 128), PsA (n= 60) and rheumatoid arthritis (RA, n= 74) patients and healthy donors (HD, n= 79).
Persisting challenges in the development of predictive biomarkers for immuno-oncology therapies for renal cell carcinoma.

Introduction Immuno-oncology (IO) therapies have become integral to renal cell carcinoma (RCC) management, RCC remains a complex malignancy with diverse clinical behaviors and a heterogeneous tumor microenvironment, highlighting the need for predictive biomarkers to optimize therapy. Areas covered This review synthesizes recent findings from clinical trials, translational studies, and molecular analyses to provide an updated perspective on biomarker research for IO therapies in RCC. A literature search was conducted using PubMed, Embase, and Web of Science for articles published between January 2010 and November 2024.

Zika virus (ZIKV) is a flavivirus of significant epidemiological importance, utilizing various transmission strategies and infecting "immune privileged tissues" during both the pre- and postnatal periods. One such transmission method may involve extracellular vesicles (EVs). EVs can travel long distances without degrading, carrying complex messages that trigger different responses in recipient cells.

Cardiac arrest (CA) is a life-threatening condition that requires immediate medical attention. Considerable advances in resuscitation have led to an increasing number of patients who survive the initial arrest event. However, among this growing patient population, morbidity and mortality rates remain strikingly high.
