Dynamic changes of mmp-9 plasma levels correlate with jvc reactivation and immune activation in natalizumab-treated multiple sclerosis patients [PDF]

, 2019
The aim of the study was to investigate the changes of matrix metalloproteinase (MMP)-2 and MMP-9 plasma levels during natalizumab treatment and their correlation with JC virus (JCV) reactivation and T-lymphocyte phenotypic modifications in peripheral ...

Usutu Virus: An Arbovirus on the Rise

Viruses, 2019
The Usutu virus (USUV) is a flavivirus that is drawing increasing attention because of its potential for emergence. First isolated in Africa, it was introduced into Europe where it caused significant outbreaks in birds, such as in Austria in 2001.

Defective viral genomes as therapeutic interfering particles against flavivirus infection in mammalian and mosquito hosts

Nature Communications, 2021
Defective viral genomes (DVGs) can interfere with virus replication and provide a potential approach to control infection. Here, Rezelj et al. use a combined experimental evolution and computational approach to identify DVG sequences that optimally ...

A High Frequency of HIV-Specific Circulating Follicular Helper T Cells Is Associated with Preserved Memory B Cell Responses in HIV Controllers

mBio, 2018
Follicular helper T cells (Tfh) play an essential role in the affinity maturation of the antibody response by providing help to B cells. To determine whether this CD4+ T cell subset may contribute to the spontaneous control of HIV infection, we analyzed ...

Exosomes containing HIV protein Nef reorganize lipid rafts potentiating inflammatory response in bystander cells. [PDF]

, 2019
HIV infection has a profound effect on "bystander" cells causing metabolic co-morbidities. This may be mediated by exosomes secreted by HIV-infected cells and containing viral factors.

Widespread and dynamic expression of granzyme C by skin-resident antiviral T cells

Frontiers in Immunology, 2023
After recognition of cognate antigen (Ag), effector CD8+ T cells secrete serine proteases called granzymes in conjunction with perforin, allowing granzymes to enter and kill target cells.

Polymicrobial periodontal disease triggers a wide radius of effect and unique virome. [PDF]

, 2020
Periodontal disease is a microbially-mediated inflammatory disease of tooth-supporting tissues that leads to bone and tissue loss around teeth. Although bacterially-mediated mechanisms of alveolar bone destruction have been widely studied, the effects of
