New “dictionary” of immune responses reveals far more complexity in the immune system than previously thought

Broad Institute

Using single-cell RNA sequencing to analyze gene expression in individual cells, the researchers have found how 86 major cytokines affect 17 immune cell types in mice. NH: This is the first single-cell resolution dictionary of each major immune cell type responding to each major cytokine in vivo at an unprecedented scale.

Why brain cancer is often resistant to immunotherapy

Broad Institute

This study provides us with the data we need to create myeloid-targeting strategies to modulate these programs and make immunotherapies more effective for brain tumor patients, said Tyler Miller, co-first author on the study and a resident in clinical pathology at Massachusetts General Hospital when the study began.

Spatial study of lung cancer reveals immune markers of response to immunotherapy

Broad Institute

doi: 10.1038/s41590-024-01792-2 (2024) Scientists used a microscope to visualize an immunity hub (yellow and green) in human lung tumor tissue (blue). They analyzed individual immune cells from human lung tumor samples taken from 68 people before they were treated with PD-1 inhibitors. Nature Immunology.

Delaying second dose of mRNA COVID-19 vaccine produces stronger immune response

The Pharma Data

The first peer-reviewed study in North America examining the timing between the first and second doses of COVID-19 mRNA vaccines shows that a longer dose interval leads to a stronger immune response. The study is funded by the Government of Canada through its COVID-19 Immunity Task Force (CITF).

Drug repurposing in SARS-CoV-2 / COVID-19: preventing the maladaptive immune response leading to critical disease requiring ICU care.

Plenge Gen

Here, I focus on a specific clinical inflection point in COVID-19 disease progression – hospitalized patients early in their disease course and with signs of a maladaptive immune response, with the intervention intended to prevent disease progression and admission to the ICU. appeared first on Plenge Gen @rplenge.

Immuno-oncology innovations redefining cancer treatment in 2024

Drug Target Review

Individualised cancer vaccines are tailored to each patient’s tumour, helping the immune system mount cancer-specific immune responses that can boost checkpoint inhibitor efficacy. Espen integrates clinical and research expertise as Director of Medical Affairs.

Targeted drug treatment leads tumor cells to imitate viral infection

Broad Institute

Reporting in Science , researchers at Massachusetts General Hospital and the Broad Institute of MIT and Harvard have made a surprising discovery about these drugs. They found that mIDH1 inhibitors trick the tumor cells into thinking they are infected with a virus, causing the immune system to mount an antiviral response.
