“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.

“Diabetes in COVID-19 patients may be transitory”

Many COVID-19 patients newly diagnosed with diabetes during hospital admission may in fact have a temporary form of the disease related to the acute stress of the viral infection, it is claimed.

New diagnoses have plummeted in the pandemic

New diagnoses of common chronic conditions have dramatically declined during the COVID-19 pandemic, according to a new study.

"Common cold T cells protect against Covid"

A new study led by Imperial College London researchers provides the first evidence that T cells from common colds could cross-protect against infection with SARS-CoV-2.

mRNA injection to make CAR T cells

An experimental immunotherapy can temporarily reprogramme patients’ immune cells to attack a specific target via a single injection of messenger RNA (mRNA), similar to the mRNA-based COVID-19 vaccines, according to a new study.
