Nat Commun

January 2025

Dept. of Microbiology and Immunology, Center for Microbial Pathogenesis and Host Inflammatory Responses, and Winthrop P. Rockefeller Cancer Institute, University of Arkansas for Medical Sciences, Little Rock, AR, USA.

Gammaherpesviruses are DNA tumor viruses that establish lifelong latent infections in lymphocytes. For viruses such as Epstein-Barr virus and murine gammaherpesvirus 68, this is accomplished through a viral gene-expression program that promotes cellular proliferation and differentiation, especially of germinal center B cells. Intrinsic host mechanisms that control virus-driven cellular expansion are incompletely defined.

Maternal adverse childhood experiences and lifetime experiences of racial discrimination: Associations with current household hardships and intergenerational health.

Soc Sci Med

January 2025

Department of Pediatrics, Chobanian & Avedisian School of Medicine, Boston University, Boston, MA, USA; Department of Health Law, Policy & Management, Boston University School of Public Health, Boston, MA, USA.

Growing evidence shows parents' exposure to adverse childhood experiences (ACEs) and lifetime experiences of racial discrimination (EOD) negatively impacts not only their own health, but also their children's health. ACEs and EOD can be conceptualized as a reflection of shared underlying adversities and structural injustices that manifest in inequitable educational and employment opportunities and differential treatment by public policies and programs that impede parents' capacity to support their families. Therefore, a potentially important, but underexplored, mechanism of effects of parent ACEs and EOD on the next generation is through effects on household material hardships.

Background: Tumour-infiltrating T cells can mediate both antitumour immunity and promote tumour progression by creating an immunosuppressive environment. This dual role is especially relevant in hepatocellular carcinoma (HCC), characterised by a unique microenvironment and limited success with current immunotherapy.

Objective: We evaluated T cell responses in patients with advanced HCC by analysing tumours, liver flushes and liver-draining lymph nodes, to understand whether reactive T cell populations could be identified despite the immunosuppressive environment.

Animals can respond differently to shifting thermal variability versus thermal averages, both of which are changing due to climate warming. How these thermal variables affect parental care behaviors can reveal the ability of parents to modify their behaviors to meet the competing demands of their offspring's thermal needs and self-maintenance, which becomes critical in suboptimal thermal conditions. Further, the time frame used to examine the interplay between temperature and behavioral shifts (e.
