Genetic risk for asthma may be mediated through altered gene expression in the airway cells

A significant amount of genetic risk for asthma is likely mediated through altered gene expression within the airway epithelium.

Croup: A previously unrecognized complication of COVID-19 in young children

The omicron surge has led to a previously unrecognized complication of COVID-19 in young children: croup. In the first peer-reviewed report to date, physicians at Boston Children's Hospital describe 75 children who came to the hospital's emergency department (ED) with croup and COVID-19 from March 1, 2020 through January 15, 2022.

Study reveals differential blood glycoprotein profiles in symptomatic and asymptomatic COVID-19 patients

A new study used glycoprotein profiling technology platform that couples high-resolution LC-MS for glycoprotein analysis in regards to COVID-19.

Clinical trial of novel rabies vaccine in human volunteers begins in Tanzania

The University of Oxford and the Ifakara Health Institute today announced the vaccination of the first participants in a Phase Ib/II trial testing a novel rabies vaccine in human volunteers in Tanzania.

Study suggests recent common cold may actually lead to worse COVID-19 disease

A new study published in the Journal of Infectious Diseases shines an unexpected light on the notion that pre-existing immunity to common cold coronaviruses can protect us from coronavirus disease 2019 (COVID-19) – and reveals that this may actually put certain individuals at risk of more severe clinical presentations.

Third-party physicians prescribe more antibiotics through telehealth than hospital-affiliated doctors

During the COVID-19 pandemic, the demand for telemedicine boomed – increasing 63-fold among Medicare users alone from approximately 840,000 telehealth visits in 2019 to 52.7 million in 2020.

Longitudinal analysis of CD4+ T cells and antibody responses to common cold coronaviruses

Scientists have recently revealed that memory T cell responses to common cold coronaviruses stably persist for a long time.

Study finds antigenic profile of Omicron RBD is distinct from the prior SARS-CoV-2 variants of concern

A new study aimed to clarify whether extensive RBD mutations could affect the magnitude and immunodominance hierarchy of the host antibody response.

New finding may aid in development of vaccines against future animal-to-human viral diseases

A future vaccine providing protection against a wide range of coronaviruses that jump from their original animal hosts to humans - including SARS-CoV-2, the cause of COVID-19 - may be possible, say Johns Hopkins Medicine researchers, based on findings from their recent study.

Researchers discover mechanism behind loss of smell in people with COVID-19

Researchers have discovered a mechanism that may explain why people with COVID-19 lose their sense of smell.

2 Feb 2022

Prion-like domains in SARS-CoV-2 RBD and ACE2 play important functional roles in viral adhesion and entry

Scientists have recently detected and analyzed viral PrDs in the S protein of SARS-CoV-2, which are the novel regulators of virion assembly.

31 Jan 2022

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.

25 Jan 2022

Evaluation of cross-reactive T cell responses between SARS-CoV-2 and common-cold human coronaviruses

A new study investigated SARS-CoV-2 spike protein responses targeted by cross-reactive T cells that were isolated from convalescent COVID-19 individuals along with previously uninfected donors.

25 Jan 2022

SARS-CoV-2 breakthrough infections elicit potent neutralizing antibody responses

A recent study looked at the strength, durability and breadth of neutralizing antibody responses generated by breakthrough infections in individuals vaccinated against SARS-CoV2.

20 Jan 2022

Research shows a relationship between increased SARS-CoV-2 seroreactivity and antimalarial humoral immunity

Researchers investigate the cross-reactivity of the SARS-CoV-2 with pre-pandemic malaria-exposed sera samples collected from Cambodia.

Scientists support the rollout of portable CO2 monitors to UK schools

UK schools have received more than 300,000 CO2 monitors as part of a government initiative to reduce COVID-19 spread in classrooms.

17 Jan 2022

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.

13 Jan 2022

A common cold may boost the immune system against COVID-19

A recent groundbreaking research paper published in the journal Nature Communications reveals the association of circulating SARS-CoV-2-specific T cells at exposure with lack of infection – implying the protective role for cross-reactive immune T cells in coronavirus disease 2019 (COVID-19) and opening the door for second-generation vaccines that could circumvent spike-antibody immune escape variants.
