'Cold' tumors can be turned 'hot' with extremely low doses of radiation, study shows

A Ludwig Cancer Research study conducted in both mice and a small group of patients with advanced cancers has shown that so-called “cold” tumors that are nearly devoid of immune cells—and therefore unresponsive to immunotherapy—can be turned “hot” with extremely low doses of radiation and the rational use of existing therapies.

Cytokine APRIL plays a protective role against formation of atherosclerotic plaques

Heart attacks and strokes are the main causes of death and loss of productive years globally. These clinical complications are caused by atherosclerosis, which is a chronic disease that leads to the accumulation of LDL cholesterol and immune cells in the inner layer of arteries and thereby resulting in the build-up of atherosclerotic plaques.

The influence of COVID-19 on platelet activation and aggregation

In a paper recently uploaded to the bioRxiv* preprint server, humanized ACE2 mice are infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and platelets are subsequently isolated from the blood for quantitative proteomic analysis.

Scientists propose innovative method to test the effectiveness of coronavirus medicines

South Ural State University scientists have proposed an innovative method for testing the effectiveness of medicines for coronavirus. According to the researchers, it is necessary to focus on the maximum coincidence of the ligand and the receptor. The results of the work have been published in the highly-rated journal "Molecules"(Q1).

Study examines the role of programmed cell death ligands in skin immune responses

T cells are a crucial part of the human adaptive immune system. In response to a foreign invader in the body, various subsets of T cells are responsible for several functions that include killing infected cells and secreting signaling molecules called cytokines that tell other immune cells where to go and what to do.

Activation of integrins by SARS-CoV-2 may be key to infection

A new study describes the key role of membrane proteins called integrins, which are present in epithelia, in the entry and propagation of SARS-CoV-2.
