SARS-CoV-2 breakthrough infection induces virus-specific nasal T-cells

A new study reports that hybrid immunity induced by vaccination and previous infection induces SARS-CoV-2-specific tissue-resident T-cells in the nasal cavity.

Persistent viral infections within hosts cause post-acute sequelae of COVID-19, research shows

A research team, comprised of Associate Professor Tomonari Sumi of the Research Institute for Interdisciplinary Science at Okayama University and Associate Professor Kouji Harada of the Center for IT-based Education at Toyohashi University of Technology, has developed a mathematical model of the immune response within infected hosts that considers systemic infection of a novel coronavirus (SARS-CoV-2), and demonstrated by conducting experimental computer simulations that persistent viral infections within hosts potentially cause long COVID or post-acute sequelae of COVID-19.

Innovative technology reveals new insights into cellular reservoirs of HIV

In a presentation today at AIDS 2022, the 24th International AIDS Conference in Montreal, scientists with the National Institute of Allergy and Infectious Diseases' (NIAID) Vaccine Research Center (VRC) and their collaborators described how their use of cutting-edge technology revealed new insights into cellular reservoirs of HIV and what those observations could mean for the next steps in HIV cure research. NIAID is part of the National Institutes of Health.
