Article Synopsis
- Ross River virus (RRV) and Barmah Forest virus (BFV) are related viruses found in Australia and Papua New Guinea, showing evidence of convergent evolution in their genetic development.
- Analysis of multiple genomes revealed that specific mutations in key proteins are important for their replication and interaction with host cells, indicating similarities in how both viruses adapt to their environments.
- Although some mutations appear to have benefited their evolution, the overall selection pressures suggest that RRV and BFV have undergone purifying selection, maintaining stable functions during their replication in different hosts like mosquitoes and vertebrates.
Article Synopsis
- Scientists are working on using special types of stem cells called Long-term reconstituting haematopoietic stem cells (LT-HSCs) to help treat blood problems through transplants.
- One challenge is that LT-HSCs are hard to find and don’t live long in lab conditions, but researchers have made progress in keeping them alive using special support systems.
- They created a new game-changing environment using soft materials that help these LT-HSCs survive and even support gene editing, which could improve treatment for blood disorders!
In mice, γδ-T lymphocytes that express the co-stimulatory molecule, CD27, are committed to the IFNγ-producing lineage during thymic development. In the periphery, these cells play a critical role in host defense and anti-tumor immunity. Unlike αβ-T cells that rely on MHC-presented peptides to drive their terminal differentiation, it is unclear whether MHC-unrestricted γδ-T cells undergo further functional maturation after exiting the thymus.

The histone lysine demethylase 4A (KDM4A) has been established as a novel therapeutic target in AML, due to its selective oncogenic role within leukaemic cells. We identify that the transcription factor nuclear factor of activated T cells 2 (NFATC2) is a novel binding and transcriptional target of KDM4A in the human AML THP-1 cell line.
View Article and Find Full Text PDFSindbis virus (SINV) is a widely dispersed mosquito-borne alphavirus. Reports of Sindbis disease are largely restricted to northern Europe and South Africa. SINV is frequently sampled in Australian mosquito-based arbovirus surveillance programs, but human disease has rarely been reported.
