Recent outbreaks of PRRSV in live attenuated vaccine-immunized pig farms in Tianjin, China have raised questions about the etiological characteristics and pathogenicity of the PRRSV variant, which remains unknown. In this study, a multiple lineages recombinant PRRSV strain named TJ-C6, was isolated and identified. Phylogenetic trees and genome homology analyses revealed that TJ-C6 belonged to lineage 1.

Purpose Of Review: Long-term immune related adverse events (irAEs) are an increasing reality in cancer patients treated with immune checkpoint inhibitors (ICIs) but remain under-reported. With the number of ICI treated patients increasing, we here aimed to expose the current evidence on their clinical presentations and diagnosis criteria.
Recent Findings: First described in ICI validation trials, long term irAEs were further characterized through retrospective studies, providing clues on their frequency, clinical spectrum, risk factors and impact on patient's quality of life.
NK Count and Natural Cytotoxicity in Immune Nonresponders Versus Responders Living With HIV.

February 2025
Infectious Diseases Department, University Hospital Montpellier & INSERM U1175, University Montpellier, Montpellier, France.
Despite viral suppression with antiretroviral therapy, immune nonresponders (INR) among people living with HIV (PLWH) still have a higher risk of developing AIDS-related and non-AIDS-related complications. Our study aimed to investigate the phenotype and functions of Natural Killer (NK) cells in INR, to better understand underlying mechanisms of immune nonresponse. Our cross-sectional study included PLWH aged over 45 with an undetectable HIV viral load sustained for at least 2 years.

Alzheimers Dement
January 2025
Center for Motor Neuron Biology and Disease, Columbia University Medical Center, New York, New York, USA.
This proceedings article summarizes the inaugural "T Cells in the Brain" symposium held at Columbia University. Experts gathered to explore the role of T cells in neurodegenerative diseases. Key topics included characterization of antigen-specific immune responses, T cell receptor (TCR) repertoire, microbial etiology in Alzheimer's disease (AD), and microglia-T cell crosstalk, with a focus on how T cells affect neuroinflammation and AD biomarkers like amyloid beta and tau.

Herpesviruses, a family of large enveloped DNA viruses, establish persistent infections in a wide range of hosts. This characteristic requires an intricate network of interactions with their hosts and host cells. In recent years, the interplay between herpesviruses and the epitranscriptome-chemical modifications in transcripts that may affect mRNA biology and fate-has emerged as a novel aspect of herpesvirus-host interactions.
