Study identifies a host factor that reflects different levels of inflammation within mild COVID-19 cases

A new study investigates serum from COVID-19 convalescents and uninfected individuals to determine the molecular mechanisms of host responses.

Researchers explain why decaying SARS-CoV-2 antibodies in blood are not a problem after vaccination

A new study published in the preprint bioRxiv* server suggests vaccination helps to inflate the number of somatic hypermutations acquired by B cells. The increase in somatic hypermutations allows for an accumulation of highly matured bone marrow plasma cells.

SARS-CoV-2 variants neutralized by camel nanobodies

Researchers from the US recently isolated two VHH nanobodies - 7A3 and 8A2 - from dromedary camels (Camelus dromedaries) using phage display. These nanobodies were found to have a high affinity for the spike RBD and broad neutralization abilities against SARS-CoV-2 and its variants.

Engineered 3D scaffolds of human brown adipose tissue as a new therapeutic strategy for obesity and diabetes

A group of researchers from various institutes in the USA addressed the limitations of BAT therapy by transplanting a low dose of brown adipocytes (BAs) without Matrigel to determine if this could alleviate high-fat diet-induced OB, metabolic symptoms, and T2DM in mice.

Research finds different antibody responses following COVID vaccination and natural infection

A new study published in the journal Nature attempted to investigate memory B cell evolution 5 months after vaccination with mRNA vaccines such as Moderna (mRNA-1273) or Pfizer-BioNTech (BNT162b2) in SARS-CoV-2 naïve individuals. The study explored various aspects of memory B cell antibody response like neutralizing response, affinity, epitope targeting, and neutralizing breadth.

Non-severe COVID-19 may elicit more durable memory B cell response than severe COVID-19

A recent study conducted by researchers from the US aimed to measure the impact of severity of COVID-19 on memory B cell response and characterize changes in the memory B cell compartment during the period between recovery and five months after symptom onset. This study is available on the bioRxiv* preprint server.

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.
