Study shows enduring T-cell immunity up to at least 1-year after SARS-CoV-2 infection

A new study assesses SARS-CoV-2 antigen-specific cytokine responses in a cohort of SARS-CoV-2 infected individuals with varying levels of disease.

Cross-recognition of SARS-CoV-2 vaccine-elicited T cell responses among different variants

In a new study, researchers evaluated SARS-CoV-2 vaccination-induced T cell responses cross-recognition among the early and novel SARS-CoV-2 variants.

SARS-CoV-2 infection and vaccination-induced T cells cross-recognize Omicron

In a recent study posted to the Nature In Review* preprint server, researchers performed a comprehensive, in-depth comparison of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific T cell epitope repertoire following natural infection of coronavirus disease 2019 (COVID-19) compared to messenger ribonucleic acid (mRNA) vaccinations.

Exploring loss of Y chromosome in white blood cells as a risk-factor of life-threatening COVID-19 in men

Researchers published a study exploring the possibilities of predisposing men for a life-threatening disease course of COVID-19.

Study suggests myeloid cell dysregulation is a driver of COVID-19 severity

Researchers determine the driving factors for disease severity and death due to COVID-19.

The unique T cell response elicited by SARS-CoV-2 during a primary immune response by infection and vaccination

The distinctive characteristics of the T cell response generated by SARS-CoV-2 infection and vaccination and the relationship to CCCoVs and VOC was explored in a review published in Frontiers in Medicine.

Withdrawing steroid treatment found to boost SARS-CoV-2 vaccine-induced immunity in kidney transplant recipients

In a new study, a team of researchers investigated the impact of the fourth dose of a vaccine against COVID-19 in kidney transplant recipients, who had not mounted a humoral immune response to three doses of vaccine.

Researchers compare survival rates of AML patients treated with two forms of transplantation methods

Acute myeloid leukemia (AML) is a common type of blood cancer that has a relatively low survival rate. It is particularly deadly for patients suffering from refractory and relapsed AML (R/R AML), meaning their cancer has stopped responding to treatment and has returned after a period of remission.

SARS-CoV-2 spike T cell responses from vaccines or infection remain robust against Omicron

In a new study, a team of researchers from multi-national institutions discovered that 70-80% of CD4 and CD8 T cell responses to spike were consistent across research groups. Moreover, although having far more mutations, the magnitude of Omicron cross-reactive T cells was comparable to that of the Beta and Delta variants.

Third BNT162b2 dose effectively neutralizes SARS-CoV-2 Omicron pseudovirus

The findings reveal that the Omicron neutralizing titers induced by the third vaccine dose are comparable to that achieved against the original Wuhan strain (wild-type SARS-CoV-2) by the two-dose regimen. The study is currently available on the medRxiv* preprint server while awaiting peer review.

Investigating potential cross-protection against SARS-CoV-2 after previous exposure to bovine coronavirus

Researchers have conducted an investigation to probe the similarity of viral epitopes between bovine coronavirus (BCoV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

T cell responses remain broadly robust against Omicron variant of SARS-CoV-2

A new study highlights the significance of robust T cell responses in preventing severe omicron infections.

COVID-19 in association with pre-existing mental and physical health issues

The present study attempts to identify the factors that increase the risk of COVID-19 infection or confer protection against COVID-19 in a study population above 55 years of age known to experience higher morbidity and risk of mortality from COVID-19.

13 Dec 2021

A novel reverse epitope discovery approach to characterize SARS-CoV-2 public CD4+ αβ T cell clonotypes

A new study, published on the bioRxiv* preprint server, has focused on public clonotypes, i.e., clones found in multiple individuals, for the development of a novel reverse epitope discovery technique. This technique holds greater potential for population-wide applications.

What are the anti-COVID drugs currently in development?

The first antiviral drugs effective against COVID-19 were recently approved in the UK and USA. A researcher from the Laboratory of Gene Technology has been exploring what we know so far.

Study assesses T-cell responses directed against highly conserved regions of SARS-CoV-2

The study aimed to assess whether highly conserved regions within coronaviruses harbor CD8+ T-cell epitopes, capable of being cross-recognized between different coronaviruses.

Study reveals a link between genital warts and the human leukocyte antigen system

New research presented today at the EADV 30th Congress reveals a link between genital warts and the human leukocyte antigen system - the part of the immune system which helps regulate immune responses.

The impact of multiple sclerosis therapy on COVID-19 vaccine efficacy

In a paper, the vaccine-induced cellular and immune response of MS patients receiving a range of therapies are assessed.

Severe COVID-19 is associated with expansion of immature myeloid cells and inflammation

A team of scientists in Ireland recently identified certain immune markers that can predict the progression of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to severe coronavirus disease 2019 (COVID-19). Early detection of these predictive markers can facilitate therapeutic decision-making prior to peak severity.
