Fentanyl and its derivatives have become pervasive contaminants in the U.S. heroin supply. Previously, we reported a proof-of-concept vaccine designed to combat against heroin contaminated with fentanyl. Herein, we optimized the admixture vaccine and found that it surpassed the individual vaccines in every antinociceptive test, including a 10% fentanyl to heroin formulation. It is anticipated that other co-occurring drug abuse disorders may also be examined with admixture vaccines.

Enhancing COVID-19 Vaccine Efficacy: Dual Adjuvant Strategies with TLR7/8 Agonists and Glycolipids.

J Med Chem

The controlled release of immunostimulatory agents represents a promising strategy to enhance vaccine efficacy while minimizing side effects. This study aimed to improve the efficacy of the RBD-Fc-based COVID-19 vaccine through combining of an iNKT cell agonist and a TLR7/8 agonist using covalent conjugation and temporal delivery. We hypothesized that these combinations would yield a more balanced Th1/Th2 immune response.

Backgrounds: Malaria, a preventive and treatable disease, is still responsible for annual deaths reported in most tropical regions, principally in sub-Saharan Africa. Subunit recombinant transmission-blocking vaccines (TBVs) have been proposed as promising vaccines to succeed in malaria elimination and eradication. Here, a provisional study was designed to assess the immunogenicity and functional activity of alanyl aminopeptidase N (APN1) of Anopheles stephensi, as a TBV candidate, administered with MPL, CpG, and QS21 adjuvants in the murine model.

Article Synopsis
  • HPV vaccines show promise in fighting HPV-related cancers, but clinical success has been challenging.
  • Recent studies using spherical nucleic acids (SNAs) with a specific peptide (E7) and a CpG adjuvant demonstrated superior immune responses in humanized mice, particularly with distinctive oligonucleotide anchors.
  • Stronger anchors improved T-cell responses and dendritic cell activation, emphasizing the importance of structural design for effective therapeutic vaccines.

, , and are three of the most widespread vectors of malaria parasites, with geographical ranges stretching across wide swaths of Africa. Understanding the population structure of these closely related species, including the extent to which populations are connected by gene flow, is essential for understanding how vector control implemented in one location might indirectly affect vector populations in other locations. Here, we assessed the population structure of each species based on a combined data set of publicly available and newly processed whole-genome sequences.

Transdermal delivery of peptide drugs is almost impossible with conventional penetration enhancers because of epidermal barrier function. Microneedle (MN) patches can bypass the epidermal barrier and have been developed for trans- and intradermal delivery of peptide drugs and vaccines. However, dissolving MN patches are limited by low drug loading capacities due to their small size and admixture of drug and water-soluble excipients.
