The innate/general resistance system and the adaptive system are the two main subsystems of the immune system. To generate an efficient immune response, the innate and adaptive systems constantly ...

Covid-19 denotes coronavirus disease 2019, CT computed tomography, ICU intensive care unit, MIS-C multisystem inflammatory syndrome in children, ND not determined, PASC postacute sequelae of Covid-19, ...

In a recent study posted to the medRxiv* preprint server, researchers evaluated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence and population-level humoral immunity among ...

Maintenance of long-term antibody responses is critical for protective immunity against many pathogens. However, the duration of humoral immunity and the role played by memory B cells remain poorly ...

The use of a monoclonal antibody that reduced circulating IgG levels, led to a decrease in preexisting neutralizing antibodies (NAbs) to adeno-associated virus (AAV). The study, which showed that this ...

Just as robust stone walls and expansive moat waters protect a castle and its inhabitants from foreign intruders, the body’s adaptive immunity mounts two defensive arms against pathogens: B cells and ...

This is a comparative study on seroconversion to chicken infectious anemia virus (CIAV) in a closed flock of specific-pathogen-free chickens undergoing a natural outbreak and after vaccination of some ...

Humoral immunity produces antigen-specific antibodies and is primarily driven by B cells. Cell-mediated immunity on the other hand does not depend on antibodies for its adaptive immune functions and ...

One can acquire humoral immunity to a specific infection or disease if administered with antibodies from someone who was previously been exposed to the same infection, circumventing the humoral ...
