Activated Hepatic Stellate Cell-Derived Bmp-1 Induces Liver Fibrosis via Mediating Hepatocyte Epithelial-Mesenchymal Transition

[Cell Death & Disease] Researchers investigated the roles and mechanisms of Periostin in phenotypic transition of hepatic stellate cells and relevant abnormal cellular crosstalk during liver fibrosis.

Systematic Detection of Co-Infection and Intra-Host Recombination in More than 2 Million Global SARS-CoV-2 Samples

[Nature Communications] Researchers presented a comprehensive analysis of more than 2 million SARS-CoV-2 raw read datasets submitted to the European COVID-19 Data Portal to identify co-infections and intra-host recombination.

Vaccine Design via Antigen Reorientation

[Nature Chemical Biology] Investigators demonstrated the generalizability of this approach with antigens from Ebola, SARS-CoV-2, and influenza viruses and observe enhanced neutralizing antibody responses in all cases.

Brain Glucose Induces Tolerance of Cryptococcus neoformans to Amphotericin B During Meningitis

[Nature Microbiology] Through a systematic evaluation of metabolite–drug–fungal interactions in the leading fungal meningitis pathogen, Cryptococcus neoformans, scientists found that brain glucose induces fungal tolerance to amphotericin B in mouse brain tissue and patient cerebrospinal fluid via the fungal glucose repression activator Mig1.

Safety and Protective Efficacy of PfSPZ Vaccine Administered to HIV Negative and Positive Tanzanian Adults

[Journal Of Clinical Investigation] Investigators conducted a clinical trial to assess the safety and efficacy of Plasmodium falciparum sporozoites Vaccine in HIV-positive individuals since the HIV infection status of participants in mass vaccination programs may be unknown.

Increasing HbA1c Is Associated with Reduced CD8+ T Cell Functionality in Response to Influenza Virus in a TCR-Dependent Manner in Individuals with Diabetes Mellitus

[Cellular And Molecular Life Sciences] Researchers stimulated peripheral blood mononuclear cells from donors with and without diabetes with influenza A virus, anti-CD3/anti-CD28-coated beads, PMA and ionomycin, or an influenza viral peptide pool.
