Data reinforces SAB-185’s potential to neutralize SARS-CoV-2 variants

A study, available on the pre-print server bioRxiv*, evaluated the neutralizing capacity of a fully human polyclonal antibody (SAB-185) against the Delta, Kappa, and Lambda variants using a lentiviral-based pseudovirus assay.

How delta and kappa variants of SARS-CoV-2 evade the immune system

A new study, available on the bioRxiv* preprint server, describes the neutralizing ability of the monoclonal antibodies against the variants and the difference of the ACE2 binding affinity found in the variants.

In Southeast Asia, robust immunity found up to 9 months after SARS-CoV-2 infection

Now, a new study posted to the bioRxiv* preprint server focuses on functional immune memory to SARS-CoV-2, up to nine months in a Southeast Asian cohort, in the absence of re-infection.

Vaccinating previously infected induces more potent antibodies less susceptible to escape from SARS-CoV-2 variants

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causal agent of the coronavirus disease 2019 (COVID-19) pandemic, which has claimed more than 4.3 million lives worldwide. Even after implementing various measures, such as vaccination and social restrictions, SARS-CoV-2 and its variants of concern (VoC) leave the world's public health systems and economies in turmoil.

Penn researchers reveal complex details of T-cell responses to mRNA COVID-19 vaccines

Messenger-RNA (mRNA) vaccines against the coronavirus that causes COVID-19 provoke a swift and strong response by the immune system's T cells-;the heavy armor of the immune system-;according to a study from researchers in the Perelman School of Medicine at the University of Pennsylvania.

Obtained SARS-CoV-2 immunity, naturally or via vaccination persists 12 months

In a research paper recently uploaded to the preprint server medRxiv* by Havervall et al. (August 12th, 2021), neutralizing antibody titers towards wild-type SARS-CoV-2 and several variants of concern in individuals having either been vaccinated or infected with mild COVID-19 one year earlier are assessed, finding a reduced neutralization capacity against some strains.

Researchers assess the genetic features of T-cell immunity development to SARS-CoV-2 variants

The continuing emergence of new SARS-CoV-2 mutations allows the virus to spread more effectively and evade antibodies. However, it is unclear whether new strains are capable of evading T-cell immunity-; one of the body's main lines of defense against COVID-19.

SARS-CoV-2 Spike may trigger production of antibodies that cross-react with human thrombopoietin to induce thrombocytopenia

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infected individuals often suffer from thrombocytopenia, a condition associated with low platelet counts. The cytokine thrombopoietin regulates platelet count. Previous studies have reported that thrombocytopenia can increase the coronavirus disease 2019 (COVID-19) mortality rate by about five times.

Certain intestinal bacteria induce cross-reactive IgA responses to the SARS-CoV-2 spike RBD

A new study finds that human gut bacteria can induce antibodies of the immunoglobulin A (IgA) subtype that cross-react with the SARS-CoV-2 spike RBD.

Quick, inexpensive leptospirosis test strip kit to help lower death and disability risk

The Faculty of Medicine, Chulalongkorn University has brought out a quick, inexpensive, and easy-to-use leptospirosis test strip kit to help lower the risk of disability from internal organ failure and death, with the hopes of distributing them to community hospitals across the country.

World-first trial of third dose COVID-19 booster vaccine shows improved protection in transplant patients

Scientists with the Ajmera Transplant Centre at UHN have conducted a first-in-the-world randomized placebo-controlled trial of third dose COVID-19 booster vaccine for transplant patients that shows substantially improved protection.

Study illuminates the link between cholesterol and Alzheimer's-associated toxic protein clumps

A team co-led by scientists at Scripps Research has used advanced imaging methods to reveal how the production of the Alzheimer's-associated protein amyloid beta (Aβ) in the brain is tightly regulated by cholesterol.

‘I don’t want to risk my life for a paycheck’: Immunosuppressed people grapple with returning to work

Elizabeth Groenweghe got a kidney transplant 14 years ago. She now takes several medications to prevent her body from rejecting her transplant organ. But these medications also weaken her immune system, putting her at higher risk of becoming seriously ill if she catches covid-19.

L452R mutations may have triggered the emergence of several COVID-19 variants

Most of the recently risen coronavirus variants of interest or concern -- delta, kappa, epsilon, iota and lambda -- are universally carrying a mutation in amino acid L452 of the Spike protein that helps the virus bind to host cells.
