For SARS-CoV-2, the causative agent of covid-19, the focus is mainly on IgM, IgG, and IgA antibodies that can neutralise the virus by binding to the spike and other membrane proteins and thus preventing infection.1 Understanding the lesser known roles of T cells and cellular immunity will...
we and others have applied the single-cell RNA sequencing (scRNA-seq) to profile the immune cell heterogeneity and dynamics in BALFs, blood, and respiratory tract samples from the COVID-19 patients. Collectively, those studies revealed a stunted IFN response, depletion...
which was hallmarked by the high-level expression of perforin and evidenced a status of NK cell exhaustion.9,17 Another ex vivo study analyzed the potential of peripheral blood mononuclear cells derived from patients with COVID-19 to induce an ADCC response against rituximab-coated Raji cells.18...
COVID-19 patients. Interestingly, we also found an activated immune response to some extent in the late stage of infection compared with the early stage. These data provide a map of molecular changes associated with the COVID-19 disease and provide hints as to how two-stage pathogenesis might...
Unique cell responses mean some people may be immune to catching the coronavirus, even if they are unvaccinatedBy Sonali Roy19 June 2024 Volunteers have been exposed to the coronavirus that causes covid-19 as part of a scientific study koto_feja/GETTY Deliberately exposing people to ...

The data confirm “that neutrophils are going to be very important in COVID-19,” says James Chalmers, a pulmonologist at the University of Dundee in Scotland. Chalmers was not involved in the new research but has studied neutrophils since 2008, when NETs “were the hot new thing,” he sa...
(SARS-CoV-2) infection is spreading to every continent, forcing us to live with this virus for perhaps a long time. Scientists and clinicians have learned much of coronavirus disease 2019, COVID-19, and its pathogenesis [1]: not all people exposed to SARS-CoV-2 are infected and not all...
Obesity may cause a hyperactive immune system response to COVID-19 infection that makes it difficult to fight off the virus, according to a new manuscript published in the Endocrine Society's journal, Endocrinology.
In contrast, the antibody test determines if you had COVID-19 sometime in the past. It is measuring yourbody's immune response to the infection, something that occurs over days to weeks after the infection starts. The antibody can appear after the infection is resolved, or even while you ...
