Article Abstract

Mucosal vaccines are receiving increasing interest both for protecting against infectious diseases and for inducing therapeutic immune responses to treat non-infectious diseases. However, the mucosal barriers of the lungs, gastrointestinal tract, genitourinary tract, nasal, and oral tissues each present unique challenges for constructing efficacious vaccines. Vaccination through each of these mucosae requires transport through the mucus and across specialized epithelia to reach tissue-specific immune cells and lymphoid structures, necessitating finely tuned and multifunctional strategies. Serving as inspiration for mucosal vaccine design, pathogens have evolved elaborate, diverse, and multipronged approaches to penetrate and infect mucosae. This review is focused on biomaterials-based strategies, many inspired by pathogens, for designing mucosal vaccine platforms. Passive and active technologies are discussed, along with the microbial processes that they seek to mimic.

Introduction: This study investigated the mucosal immunoadjuvant effects of Gynostemma Pentaphyllum Extract (Gynostemma P.E), the bioactive constituents of , against porcine epidemic diarrhea virus (PEDV).

Methods: Twenty-four mice were randomly divided into four groups: a negative control group (intranasal administration of antigen only), a Gynostemma P.

Introduction: The emergence of highly virulent strains of the porcine reproductive and respiratory syndrome virus has driven the need for new vaccines. This study evaluates the efficacy of an intranasal (IN) vaccine composed of a naturally attenuated PRRSV-2 isolate, compared to a commercially available intramuscularly administered (IM) PRRSV-1 vaccine, against a heterologous challenge with a highly virulent PRRSV-1 strain (R1).

Methods: Sixty-eight PRRSV-naïve pigs were divided into four groups: two non-vaccinated controls (NV/NCh, NV/Ch), one IM-vaccinated with a PRRSV-1 MLV (Por), and one intranasally (IN)-vaccinated with the PRRSV-2 vaccine (IL).

Innate-like T cells (ILT), including γδ T cells (Vδ2s), Natural Killer T cells (NKTs) and Mucosal-associated Invariant T cells (MAITs), integrate innate and adaptive immunity, playing important roles in homeostatic conditions as well as during infection or inflammation. ILT are present on both sides of the fetal-maternal interface, but our knowledge of their phenotypical and functional features in neonates is limited. Using spectral flow cytometry we characterized cord blood ILT in neonates born to healthy women and women living with HIV.

The increasing prevalence of respiratory disorders highlights the urgent need for effective mucosal vaccines that elicit targeted immune responses at pathogen entry sites. However, the advancement of mucosal vaccines is limited by challenges in antigen delivery and overcoming mucosal immune tolerance. In this study, we developed a gene delivery platform using chitosan functionalized with lactobionic acid (LA) to enhance targeting of antigen-presenting cells and to form stable DNA polyplexes with high transfection efficiency.

Mycoplasma gallisepticum (MG) is one of the main pathogens causing chronic respiratory diseases in chickens, which seriously affects the sustainable and healthy development of the poultry industry and leading to heavy economic losses. Therefore, we developed a safe, efficient, convenient, and low-cost MG oral vaccine. The vaccine is based on a recombinant yeast surface display system to compensate for the shortcomings of existing vaccines.
