Glucose-dependent insulin delivery systems have been recognized as a promising approach for controlling blood sugar levels in individuals with diabetes mellitus (DM). Recently, titanium dioxide nanoparticles have garnered huge attention in scientific research for their small size and effective drug delivery capabilities. In this study, we developed alizarin (AL)-capped phenylboronic acid (PBA)-functionalized titanium dioxide nanoparticles (TiO) for glucose-sensitive insulin delivery (TiO-PBA-INS-AL) aiming to manage both blood sugar levels and its associated organ pathology in DM.

Booster COVID-19 mRNA vaccination ameliorates impaired B-cell but not T-cell responses in older adults.

Front Immunol

December 2024

Department of Life Science Frontiers, Center for iPS Cell Research and Application (CiRA), Kyoto University, Kyoto, Japan.

Age-associated differences in the effect of repetitive vaccination, particularly on memory T-cell and B-cell responses, remain unclear. While older adults (aged ≥65 years) exhibited enhanced IgG responses following COVID-19 mRNA booster vaccination, they produced fewer spike-specific circulating follicular helper T cells-1 than younger adults. Similarly, the cytotoxic CD8 T-cell response remained diminished with reduced PD-1 expression even after booster vaccination compared with that in younger adults, suggesting impaired memory T-cell activation in older adults.

Dengue virus (DENV) is an increasingly important human pathogen, with already half of the globe's population living in environments with transmission potential. Since only a minority of cases are captured by direct detection methods (RT-PCR or antigen tests), serological assays play an important role in the diagnostic process. However, individual assays can suffer from low sensitivity and specificity and interpreting results from multiple assays remains challenging, particularly because interpretations from multiple assays may differ, creating uncertainty over how to generate finalized interpretations.

Background: SARS-CoV-2 has been associated with a higher proportion of asymptomatic infections and lower mortality in sub-Saharan Africa than high-income countries. However, there is currently a lack of data on cellular immune responses to SARS-CoV-2 in people living in Africa compared with people in high-income regions of the world. We aimed to assess geographical variation in peripheral and mucosal immune responses.

Article Synopsis
  • Helicobacter pylori is a type 1 carcinogen linked to gastric ulcers and cancer, and research by the Seattle Structural Genomics Center for Infectious Disease focuses on potential treatments targeting this bacterium.
  • The study reports on the purification and crystallization of H. pylori biotin protein ligase (HpBPL), an enzyme that plays a crucial role in important metabolic processes and helps H. pylori thrive in the acidic environment of the stomach.
  • Despite having low sequence identity with similar proteins, HpBPL shares significant structural similarities with Mycobacterium tuberculosis biotin protein ligase, indicating potential for developing inhibitors that could be effective against HpBPL.

Transmission of the malaria parasite Plasmodium to mosquitoes necessitates gamete egress from red blood cells to allow zygote formation and ookinete motility to enable penetration of the midgut epithelium. Both processes are dependent on the secretion of proteins from distinct sets of specialized vesicles. Inhibiting some of these proteins has shown potential for blocking parasite transmission to the mosquito.
