Possible impact of spike protein mutations on SARS-CoV-2 Omicron variant

The current study not only analyses the mutations in the Omicron spike variant but classifies various combinations of spike mutations into groups.

Impact of post-translational modifications in the pathogenicity of SARS-CoV-2

A new study provides understanding of the intricate roles and functions of the different elements of spike proteins and shows how the spike protein samples a crowded surface of its host cell via the glycans.

Immune response of Pfizer vaccinees who received Moderna or Pfizer booster

A new preprint discusses the immune boost resulting from homologous or heterologous booster doses in individuals fully vaccinated with two doses of the Pfizer vaccine.

Study suggests algal polysaccharide may be a promising anti-COVID-19 candidate

Researchers from the Rensselaer Polytechnic Institute have been investigating the potential of rhamnan sulfate as an antiviral agent.

Scientists develop and characterize variant-specific vaccines against SARS-CoV-2

In a recent study conducted at Yale University, USA, scientists have investigated the immunogenicity of mRNA-based coronavirus disease 2019 (COVID-19) vaccine candidates encoding the spike proteins of different severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants. The findings reveal that the vaccines induce robust immune responses against SARS-CoV-2 variants. The study is currently available on the bioRxiv* preprint server.

COVID-19 severity is correlated with T cell receptor repertoire signatures

In a new study published in the bioRxiv* preprint server, researchers found that specific TCR sequences predicted the severity of coronavirus disease 2019 (COVID-19) infection. Additionally, there was evidence of increased CDR3 sequences and changes in k-mer motifs for patients with severe illness.

SARS-CoV-2 S2 immunization as a pan-coronavirus vaccine approach

A new mouse model suggests that prior HCoV-OC43 S immunity primes neutralising antibody responses to otherwise subimmunogenic SARS-CoV-2 S exposure as well as promotes S2-targeting antibody responses.

Scientists find infection of sustentacular cells in the olfactory epithelium of COVID-19 patients

It is now widely known that COVID-19 is associated with the transient or long-term loss of olfaction (the sense of smell) but the mechanisms remain obscure.

Safety and immunogenicity of SARS-CoV-2 recombinant spike protein vaccine

Researchers have presented the results of phase 1 and phase 2 clinical trials of a SARS-CoV-2 recombinant spike protein vaccine (Abdala).

SARS-CoV-2 immune memory in mRNA vaccine recipients

Researchers measured SARS-CoV-2–specific antibody, memory B cell, and memory T cell responses in a group of healthy subjects who generated primary immune responses to two doses of mRNA vaccine compared to a group of SARS-CoV-2–recovered vaccines.

Systematic review: The involvement of bitter taste receptors in cancer

Humans have 25 different types of functional bitter taste receptors. These are found on our tongue, where they facilitate the taste perception of bitter tasting compounds. In addition, there are increasing findings that cells of extra-oral organs also have such receptors.
