SARS-CoV-2 infection and immunity in pregnancy and fetal development

A review conducted by a team of researchers from the Icahn School of Medicine at Mount Sinai, the University of Colorado, and Active Motif, Incorporated compiles information on SARS-CoV-2 virology, in utero transmission from infected pregnant mothers to fetuses, new findings on possible methods of SARS-CoV-2 cellular trafficking through exosomes, and the transcriptomic effects of SARS-CoV-2 infection, in order to inform future studies aimed at a better understanding of COVID-19 and the development of therapeutic solutions against SARS-CoV-2.

Study paves the way for development of novel delivery systems to suppress HIV

In a new study supported by the National Institutes of Health, researchers used exosomes, tiny nanoparticles capable of being taken up by cells, to deliver novel protein into the cells of mice infected with HIV. The protein attached to HIVs' genetic material and prevented it from replicating, resulting in reduced levels of HIV in the bone marrow, spleen, and brain.
