COVID-19 and subacute neuropsychiatric symptoms in adolescents

A new paper discusses neurologic symptoms in children with COVID-19.

TEDDY study adds to a growing body of evidence that type 1 diabetes is not a single disease

New findings from the international The Environmental Determinants of Diabetes in the Young (TEDDY) study add to a growing body of evidence indicating that type 1 diabetes is not a single disease. The presentation and, perhaps, cause of autoimmune diabetes differs among genetically high-risk children, the research suggests.

Fibrin immunotherapy may resolve blood clotting induced by SARS-CoV-2

A group of researchers from the United States discovered that the spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can induce the formation of highly inflammatory blood clots amenable to neutralization by a fibrin-targeting monoclonal antibody – opening the door for a completely new strategy to reduce thrombotic inflammation in coronavirus disease 2019 (COVID-19).

More than half of COVID-19 survivors experience "long COVID", researchers say

More than half of the 236 million people who have been diagnosed with COVID-19 worldwide since December 2019 will experience post-COVID symptoms -; more commonly known as "long COVID" -; up to six months after recovering, according to Penn State College of Medicine researchers.

Early-stage interaction of monocytes with SARS-CoV-2-infected epithelial cell decides COVID-19 severity

A team of scientists from the USA and France has recently unveiled the mechanism of immune dysregulation in coronavirus disease 2019 (COVID-19) patients by analyzing the early-stage interaction between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected epithelial cells and immune cells. The study is currently available on the bioRxiv* preprint server.

Evidence of persisting autoreactivity in post-acute sequelae of SARS-CoV-2 infection?

It has been demonstrated in recent studies that there is a significant breadth of emerging autoreactivity associated with severe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. More specifically, researchers from Emory University have identified a relaxation of peripheral tolerance within early antibody secretion cells that arise in individuals infected with SARS-CoV-2, as important drivers of those responses.

COVID-19 induces the generation of distinct autoantibodies

In a recent study, the association between COVID-19 and autoimmunity is investigated at all levels of disease severity.

Role of host gene variants in COVID-19 severity

A new study discusses the importance of common, rare, and intermediate variants of several host genes to the clinical severity of infection with SARS-CoV-2.

Scientists examine kids’ unique immune systems as more fall victim to covid

Eighteen months into the covid-19 pandemic, with the delta variant fueling a massive resurgence of disease, many hospitals are hitting a heartbreaking new low. They're now losing babies to the coronavirus.

IL-1-Ra autoantibodies observed in high frequency in children with PIMS/MIS-C

Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection typically affects children only mildly, multisystem inflammatory syndrome in children (MIS-C) or pediatric inflammatory multisystem syndrome (PIMS) is a serious but rare complication occurring after infection.

Severe COVID-19 linked to increase in autoantibodies

Hospitalized COVID-19 patients are substantially more likely to harbor autoantibodies -;antibodies directed at their own tissues or at substances their immune cells secrete into the blood -; than people without COVID-19, according to a new study.

Autoimmune antibodies strongly linked to the severity of illness in COVID-19 patients

The presence of special immune system defense molecules, called autoimmune antibodies, has been strongly tied to how poorly people fare when hospitalized with COVID-19, a new study shows.

How early interferon curbs SARS-CoV-2 infection

A new study available in the Journal of Experimental Medicine focuses on the importance of interferon in SARS-CoV-2 infection.

Can molecular mimicry impact fertility in female COVID-19 patients?

There exists a possibility that COVID-19 can also affect the reproductive function in the body, which can lead to infertility in infected patients. A study published in the American Journal of Reproductive Immunology explored the impact of SARS-CoV-2 infection on reproductive functions and fertility.

Study opens up a new approach to incorporating MRI into multisite pancreatic clinical trials

Researchers with the Vanderbilt Diabetes Research and Training Center (DRTC) at Vanderbilt University Medical Center led a multisite study which has demonstrated that, when controlled and standardized, quantitative magnetic resonance imaging (MRI) of the pancreas is highly reproducible when using different MRI hardware and software at different geographic locations.

Severe COVID-19 characterized by phosphorylation of STAT1

A new study reports an enhanced expression of STAT1 in mild and severely infected COVID-19 patients as compared to controls

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.

Clinical trials during a pandemic – lessons from COVID-19

In this interview, Dr. Benedicte Roquebert, Dr. Stephanie Haim-Boukobza and Dr. Souad Mehlal discuss how COVID-19 has resulted in new ways to think about clinical trials during a pandemic.

Can prior human seasonal coronavirus antibody response patterns predict SARS-CoV-2 inhibition?

A new study, recently released as a preprint on the medRxiv* server, reports the intriguing finding that the cross-neutralizing antibodies elicited by human seasonal coronaviruses (sCoVs) show varying ability to prevent binding between the SARS-CoV-2 spike antigen and its cognate receptor, the angiotensin-converting enzyme 2 (ACE2).
