Exploring the role of circulating proteins in multiple myeloma risk: a Mendelian randomization study.
Sci Rep

Population Health Sciences, University of Bristol, Bristol, UK.
Multiple myeloma (MM) is an incurable blood cancer with unclear aetiology. Proteomics is a valuable tool in exploring mechanisms of disease. We investigated the causal relationship between circulating proteins and MM risk, using two of the largest cohorts with proteomics data to-date.

Human cytomegalovirus (HCMV) encodes four viral Fc-gamma receptors (vFcγRs) that counteract antibody-mediated activation in vitro, but their role in infection and pathogenesis is unknown. To examine their in vivo function in an animal model evolutionarily closely related to humans, we identified and characterized Rh05, Rh152/151 and Rh173 as the complete set of vFcγRs encoded by rhesus CMV (RhCMV). Each one of these proteins displays functional similarities to their prospective HCMV orthologs with respect to antagonizing host FcγR activation in vitro.

The role of plasma exosomes from people living with HIV (PLWH) with HAND in the phenotypic profile of uninfected monocytes remains unknown. We hypothesized that these exosomes influence the CD14/CD16 phenotypical profile of uninfected monocytes in a time-dependent manner. Exosomes were collected via ultracentrifugation from the plasma of women living with HIV (WLWH) and healthy controls stratified according to their cognition into normal cognition (NC) or symptomatic neurocognitive impairment (SNI) groups.

Background: The coexistence of tuberculosis (TB) and lung cancer (LC) is not rare, but their causal association are underexplored. This study aims to elucidate these bidirectional correlations and investigate the mediating effects of immunophenotypes and plasma metabolites.
Methods: Genetic variants for TB and LC were sourced from the IEU Open GWAS Project, while data for 731 immunophenotypes and 1400 plasma metabolites from previously published GWAS.

Host response aimed at eliminating the infecting pathogen, as well as the pathogen itself, can cause tissue injury. Tissue injury leads to the release of a myriad of cellular components including mitochondrial DNA, which the host senses through pattern recognition receptors. How the sensing of tissue injury by the host shapes the anti-pathogen response remains poorly understood.
