An antibody is a blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.

Study suggests Omicron can be neutralized by BNT162b2 recipient sera optimally after three vaccine doses

Researchers from Westmead Hospital have been investigating the effect of a third dose on neutralizing antibody titres in already vaccinated individuals.

Omicron is more transmissible but may have milder symptoms for many people, expert says

If the first reports coming out of South Africa are correct, Omicron might be more transmissible than the current dominant Covid-19 strain, Delta, but cause less severe symptoms for many people. A leading expert says that, if the new strain does turn out to be milder for some people, that creates a new set of problems.

Evaluation of SARS-CoV-2 neutralizing antibodies in mothers and infants

A new study assessed nAb activities against five strains of SARS-CoV-2 in paired maternal and infant cord blood samples.

Evaluation of SARS-CoV-2 Omicron's immune evasion potential

Researchers use VSV vector and Omicron spike protein containing all 32 mutations to create the pseudotyped SARS-CoV-2 Omicron variant (PV-Omicron).

SARS-CoV-2 VOCs dependent on IFITM2 for efficient infection establishment

Researchers demonstrate that the Alpha, Beta, Gamma, and Delta variants of SARS-CoV-2 require endogenous IFITM2 expression for efficient replication.

Weak T-cell clonal response to SARS-CoV-2 vaccination in IBD patients deficient in antibody-responders

Researchers investigate the post-vaccination clonal T-cell response and its relationship to antibody responses in IBD patients.

Scientists develop novel method to monitor remote immune processes within cells

Our immune systems work hard to keep us healthy and to protect us against bacteria, viruses, fungi, parasites and cancerous cells.

T-cell immune response in previously infected and vaccinated individuals effective against SARS-CoV-2 Omicron variant

New findings illustrate that despite the continuous pattern of the ongoing evolution of SARS-CoV-2, it has not resulted in any significant accumulation of CD8+ T-cell escape mutations.

Impact of exogenous antibody therapy by convalescent plasma against SARS-CoV-2

Researches have been investigating the possibility of using convalescent plasma to help patients recover from COVID-19.

Cell surface expression of SARS-CoV-2 nucleocapsid protein and its role in immunity

Researchers demonstrated the unexpected roles of nucleocapsid protein in innate and adaptive immunity to SARS-CoV-2.

SARS-CoV-2 Omicron variant binding to its receptor and therapeutic entities

Researchers generated a set of computed structural models of the Omicron receptor-binding domain attached to its receptor angiotensin-converting enzyme.

Hyperbaric oxygen treatment quickly resolves severe breathing difficulties in COVID-19 patients

High pressure (hyperbaric) oxygen resolves severe breathing difficulties in COVID-19 patients much more quickly than standard therapy, taking an average of 3 rather than 9 days, reveal the results of a small comparative clinical trial published online in Emergency Medicine Journal.
