Intratumoral SIRPalpha-deficient macrophages activate tumor-specific cytotoxic T cells

In a study that will be published in Nature Communications on May 28, 2021, a research team led by Dr. Yuan Liu from Georgia State University reports that intratumoral SIRPalpha-deficient macrophages activate tumor antigen-specific cytotoxic T cells to eliminate various syngeneic cancers under radiotherapy. Their study identifies SIRPalpha as a master regulator controling macrophage immune responses and has demonstrated that intratumoral injection of SIRPalpha-depleted macrophages combined with local radiation is an effective strategy to treat different tumors ....

Chikungunya virus (CHIKV) is an arbovirus with a global spread and significant public health impact. It is a positive stranded RNA alphavirus belonging to the
Togaviridae family. However, many questions about the replication cycle of CHIKV remain unanswered. The entry process of CHIKV is not completely understood nor are the associated virus-receptor interactions fully identified. Here, we designed an affinity purification mass spectrometry coupled approach that allowed the identification of factors that facilitate entry of CHIKV in human cells. The identified entry factors were further validated using CRISP ....

The puzzle of nonhost resistance: why do pathogens harm some plants but not others?


Credit: Ralph Panstruga & Matthew Moscou
People have puzzled for years why pathogen
Phytophthora infestens causes the devastating late blight disease, source of the Irish Potato famine, on potatoes, but has no effect at all on plants like apple or cucumber. How are apple trees and cucumber plants able to completely shake off this devastating pathogen? Agricultural scientists have wondered for years: if this resistance is so complete and persists over so many generations, is there some way we could transfer it to susceptible plants like wheat and thereby stop disease?
Why is it so important to determine the molecular basis of nonhost resistance? ....
