Antibiotic resistance genes identified in TB

An analysis of more than 10,000 Mycobacterium tuberculosis bacterial isolates from 23 countries has revealed new genes associated with resistance to 13 first- and second-line new and repurposed antibiotics.

A nasal vaccine

Researchers have found the first non-infectious needle-free nasal vaccine to be effective against COVID-19. Senior study co-author Dr Venigalla B Rao explains how it works.

Non-COVID-19 respiratory infections statistics

An increase in the number of non-COVID-19 respiratory infections should be expected this winter, say scientists.

My lab: From flu to Covid to monkeypox

Panagiotis Pantelidis gives a guided tour of Infection and Immunity Sciences at North West London Pathology.

“Rare cells capable of transforming into blood cancer”

Dysfunction involving an unusual type of thymocyte cell found in small amounts in every person may be the reason why some people develop a form of leukaemia called T-cell acute lymphoblastic leukaemia (T-ALL), it is claimed.

Infectious periods in vaccinated individuals

To examine the infectious periods in vaccinated individuals infected with the SARS-CoV-2 Omicron and Delta variants, US researchers collected daily anterior nasal swabs for at least 10 days from a group of college students and staff for reverse transcription-polymerase chain reaction test and culture and with antigen rapid diagnostic testing (RDT) on a subset of individuals.

An autoimmune cause of schizophrenia?

Researchers from Tokyo Medical and Dental University (TMDU) have identified an autoantibody – a protein that is produced by the immune system to attach to a specific substance from the individual’s own body, rather than to a foreign substance, such as a virus or bacteria – in some patients with schizophrenia.

Genetic test can diagnose immune system disorders

Investigators have used next-generation sequencing to test a DNA panel of 130 different immune system genes from 22 study participants.

Memory B cells protecting against mutant viruses

Specialised memory cells found in our immune system play an important role in our ability to fight virus mutations, such as those produced by the SARS-CoV-2 virus, according to research.

“Recovering from covid can take years”

Two years after infection with COVID-19, half of patients who were admitted to hospital still have at least one symptom, according to the longest follow-up study to date.

Lupus: In search of the elusive mutation

Carola Vinuesa explains her research into lupus and what happened when a TLR7 mutation was introduced to mice using CRISPR gene-editing.
