Experimental safety switch reduces severity of CAR-T immunotherapy-related side effects


Experimental safety switch reduces severity of CAR-T immunotherapy-related side effects
UNC Lineberger Comprehensive Cancer Center researchers have successfully used an experimental safety switch, incorporated as part of a chimeric antigen receptor T-cell (CAR-T) therapy, a type of immunotherapy, to reduce the severity of treatment side effects that sometimes occur. This advance was seen in a patient enrolled in a clinical trial using CAR-T to treat refractory acute B-cell leukemia. It demonstrates a proof-of-principle for possible expanded use of CAR-T immunotherapy paired with the safety switch.
The researchers published their findings in the journal
Blood as an ahead-of-print publication.
With CAR-T therapy, T-cells from a patient s immune system are modified in a manufacturing facility to express part of an antibody that can bind to a surface protein on cancer cells. The modified T-cells, after being infused back into the patient, seek out and attack cancer ce ....

Innovative cancer treatment effective in combating fungal infection in vitro and in mice


Innovative cancer treatment effective in combating fungal infection in vitro and in mice
An innovative cell-based treatment for cancer has been found promising for the control of infections caused by fungi. A study published in the journal
Cytotherapy reports that the use of CAR (chimeric antigen receptor) T-cells programmed to recognize
Cryptococcus spp. fungi was effective in combating infection in vitro and in mice.
C. gattii and
C. neoformans are present in soil with dead organic matter and places contaminated by the droppings of pigeons and other birds. They cause systemic mycoses in the human organism. They can infect the lungs and central nervous system, causing meningitis or meningoencephalitis. The symptoms vary according to the site of the infection, which can be fatal. Transmission occurs by inhalation of the fungi. ....

SARS-CoV-2 escapes host immune responses by modulating dendritic cell maturation


SARS-CoV-2 escapes host immune responses by modulating dendritic cell maturation
A team of scientists from Italy and the USA has recently explored the maturation pattern of conventional dendritic cells (cDCs) during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Their findings reveal that the virus efficiently escapes host immune responses by directly interacting with cDCs and disrupting T cell activation. The study is currently available on the
Background
Since its emergence in December 2019 in China, SARS-CoV-2, the causative pathogen of coronavirus disease 2019 (COVID-19), has infected 114 million people and claimed 2.5 million lives worldwide. In its milder form, COVID-19 is mainly associated with fever, dry cough, sore throat etc. However, a severe form of the disease often leads to serious health complications characterized by cardiovascular, pulmonary, and metabolic disorders. In general, COVID-19 patients with severe symptoms exhibit s ....
