Review sheds light on the emergence and detection of antibiotic resistance in bioaerosols

Bioaerosols, or airborne biological particles containing viruses, fungal spores, bacteria, and pollen, play a key role in public health. Antibiotic resistance (AR), caused by antibiotic resistance genes (ARGs), could potentially cause global public health crises owing to horizontal gene transfer between same or similar bacterial bioaerosols.

Study shows long COVID remodeling of T cell dynamics is dependent on SARS-CoV-2 severity

A new study found that the post-COVID-19 functional remodeling of T cells occurs in two steps and confers different convalescent immune states, six months after SARS-CoV-2 infection.

South African study shows COVID severity of Omicron BA.1, BA.4, BA.5 all similar

A recent article posted to the medRxiv* preprint server analyzed the illness severity of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron BA.4/BA.5 and prior viral waves in the Western Cape, South Africa.

How to develop an "all-variant" COVID vaccine

In a recent study published in Nature Immunology, researchers summarized their observations of humoral immune responses elicited in severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infected people. Additionally, they discussed all the types of SARS-CoV-2 infection- and vaccine-induced neutralizing antibodies (nAbs).

Immune particles from llama blood could offer protection against several COVID-19 variants

Mount Sinai-led researchers have shown that tiny, robust immune particles derived from the blood of a llama could provide strong protection against every COVID-19 variant, including Omicron, and 18 similar viruses including SARS-CoV-2 and SARS-CoV-1, which was responsible for the 2003 SARS outbreak.

Memory B cells can be localized in the lungs, research shows

How can we increase the efficacy of vaccines used to protect against viral respiratory diseases such as influenza and COVID-19? Scientists from Inserm, CNRS and Aix-Marseille Université at the Center of Immunology Marseille-Luminy are opening up new prospects in the field, with the triggering of memory B cells directly in the lungs looking to be a promising avenue.

Study explores antibody responses following three COVID vaccine doses in kidney transplant recipients

In a recent study posted to the medRxiv* pre-print server, Canadian researchers evaluated antibody responses in kidney transplant recipients (KTRs) before and one and three months after receiving the third dose of a messenger ribonucleic acid (mRNA)-based coronavirus disease 2019 (COVID-19) vaccine.

Acute COVID-19 and vaccination induce cross-reactive antibody responses in breast milk

IgA and IgG in human breast milk and blood were assessed for their activity against SARS-CoV-2 and SARS-CoV-1, as well as four other prevalent HCoVs.

Study identifies a new mechanism that explains how immune cells learn to discern friend from foe

The human immune system is a nearly perfect defense mechanism. It protects the body from disease-causing bacteria, viruses, and other pathogens. It detects nascent tumors and eradicates them. It cleans up cellular debris at the site of injury or infection.

Evolution of SARS-CoV-2 genomes based on continuing positive selection

Researchers hypothesized that ongoing positive selection strongly influences SARS-CoV-2 genomes, which plays an important role in shaping the dynamics of the COVID-19 pandemic.
