The development of vaccines plays a vital role in the effective control of several fatal diseases. However, effective prophylactic and therapeutic vaccines have yet to be developed for completely curing deadly diseases, such as cancer, malaria, HIV, and serious microbial infections. Thus, suitable vaccine candidates need to be designed to elicit appropriate immune responses. Nanotechnology has been found to play a unique role in the design of vaccines, providing them with enhanced specificity and potency. Nano-scaled materials, such as virus-like particles, liposomes, polymeric nanoparticles (NPs), and protein NPs, have received considerable attention over the past decade as potential carriers for the delivery of vaccine antigens and adjuvants, due to their beneficial advantages, like improved antigen stability, targeted delivery, and long-time release, for which antigens/adjuvants are either encapsulated within, or decorated on, the NP surface. Flexibility in the design of nanomedicine allows for the programming of immune responses, thereby addressing the many challenges encountered in vaccine development. Biomimetic NPs have emerged as innovative natural mimicking biosystems that can be used for a wide range of biomedical applications. In this review, we discuss the recent advances in biomimetic nanovaccines, and their use in anti-bacterial therapy, anti-HIV therapy, anti-malarial therapy, anti-melittin therapy, and anti-tumor immunity.

Interleukin-12 (IL-12) is a robust proinflammatory cytokine that activates immune cells, such as T cells and natural killer cells, to induce antitumor immunity. However, the clinical application of recombinant IL-12 has been limited by systemic immune-related adverse events (irAEs) and rapid degradation. To address these challenges, we employed mRNA technology to encode a tumor-activated IL-12 "lock" fusion protein that offers both therapeutic efficacy and systemic safety.

Background: A secondary Pasteurella multocida (Pm) infection following Mycoplasma ovipneumoniae (Mo) challenge in sheep results in severe respiratory disease. Scavenger receptor A (SRA) is a key phagocytic receptor on macrophages, which facilitates microbial clearance. However, the role of sheep SRA in Mo-associated secondary Pm infection is less understood.

Various cancer therapeutic strategies have been designed for targeting tumor-associated macrophages (TAMs), but TAM reprogramming-based monotherapy is often clinically hindered, likely due to the lack of a coordinated platform to initiate T cell-mediated immunity. Herein, we fabricated reactive oxygen species (ROS)-responsive human serum albumin (HSA)-based nanoparticles (PEG/IL12-IA NPs) consisting of indocyanine green (ICG), arginine (Arg), and interleukin 12 (IL12). Upon laser irradiation, the nanoparticles were found to be able to dissociate, thus facilitating the release of IL12.

The COVID-19 pandemic brought unprecedented global challenges. Amid the crisis, the potential impact of COVID-19 exposure on the neurodevelopment of offspring born to infected mothers emerged as a critical concern. This is a prospective cohort study of pregnant women and their offspring enrolled in the Signature project at Hospital Universitario Virgen del Rocio in Seville, Spain, between 01/01/2024 and 08/31/2022.

Introduction: Lactate has emerged as a multifunctional signaling molecule regulating various physiological and pathological processes. Furthermore, lactylation, a newly identified posttranslational modification triggered by lactate accumulation, plays significant roles in human health and diseases. This study aims to investigate the roles of lactate/lactylation in respiratory diseases.
