Many vaccines have been produced during the COVID-19 pandemic. Currently, an increasing number of vaccines have reached an expiration date without being used. Therefore, expired vaccines (EXVAX) based on virus-like particles (VLP) recombinant SARS-CoV2-S protein can be repurposed for biosensing application and provide a use, even though they are past their expiration date for vaccination.

METTL3 is the RNA methyltransferase predominantly responsible for the addition of N-methyladenosine (mA), the most abundant modification to mRNA. The prevalence of mA and the activity and expression of METTL3 have been linked to the appearance and progression of acute myeloid leukemia (AML), thereby making METTL3 an attractive target for cancer therapeutics. We report herein the discovery and optimization of small-molecule inhibitors of METTL3, culminating in the selection of as an proof-of-concept compound.

Cardiovascular and cardiometabolic diseases are leading causes of morbidity and mortality worldwide, driven in part by chronic inflammation. Emerging research suggests that the bone marrow microenvironment, or marrow niche, plays a critical role in both immune system regulation and disease progression. The bone marrow niche is essential for maintaining hematopoietic stem cells (HSCs) and orchestrating hematopoiesis.

Some of the most crucial turning points in the treatment strategies for some major infectious diseases including AIDS, malaria, and TB, have been reached with the introduction of antimicrobials and vaccines. Drug resistance and poor effectiveness are key limitations that need to be overcome. Conventional liposomes have been explored as a delivery system for infectious diseases bioactives to treat infectious diseases to provide an efficient approach to maximize the therapeutic outcomes, drug stability, targetability, to reduce the side-effects of antimicrobials, and enhance vaccine performance where necessary.

Department of Chemistry, Korea Advanced Institute of Science and Technology (KAIST), Daejeon 34141, Republic of Korea.
The deposition of amyloid-β (Aβ) aggregates and metal ions within senile plaques is a hallmark of Alzheimer's disease (AD). Among the modifications observed in Aβ peptides, -terminal truncation at Phe4, yielding Aβ, is highly prevalent in AD-affected brains and significantly alters Aβ's metal-binding and aggregation profiles. Despite the abundance of Zn(II) in senile plaques, its impact on the aggregation and toxicity of Aβ remains unexplored.
