Data presented here demonstrate multifunctional vaccination strategies that harness vaccinia virus mediated delivery of a gene encoding an immunoenhanced diabetes autoantigen in combination with complete Freund's adjuvant (CFA) that can maintain safe and durable immunologic homeostasis in NOD mice. Systemic coinoculation of prediabetic mice with recombinant vaccinia virus rVV-CTB::GAD and undiluted or 10-fold diluted CFA demonstrated a significant decrease in hyperglycemia and pancreatic islet inflammation in comparison with control animals during 17-61 and 17-105 weeks of age, respectively. Synergy in these beneficial effects was observed during 43-61 and 61-105 wks of age, respectively. Inflammatory cytokine and chemokine levels in GAD-stimulated splenocytes isolated from vaccinated mice were generally lower than those detected in unvaccinated mice. The overall health and humoral immune responses of the vaccinated animals remained normal throughout the duration of the experiments.

Background: Hyperbaric Oxygen Therapy (HBO) is a treatment modality that exposes patients to 100% oxygen at higher atmospheric pressures. Recently, HBO has emerged as a potential therapeutic option for various liver diseases, offering advantages such as improved tissue oxygenation, anti-inflammatory effects, enhanced wound healing, and potential hepatoprotective properties. Understanding the benefits of HBO in liver diseases can pave the way for novel therapeutic strategies and improved patient outcomes.

Cyclic peptides are often used as scaffolds for the multivalent presentation of drug molecules due to their structural stability and constrained conformation. We identified a cyclic deca-peptide incorporating lipoamino acids for delivering T helper and B cell epitopes against group A Streptococcus (GAS), eliciting robust humoral immune responses. In this study, we assessed the function-immunogenicity relationship of the multi-component vaccine candidate (referred to as VC-13) to elucidate a mechanism of action.

Background: Multiple sclerosis (MS) is a chronic, immune-mediated neurological disorder in which the immune system mistakenly attacks the myelin sheath, affecting the communication between the brain and the rest of the body.
Objective: This study investigated the prophylactic use of peptide inhibitor of trans-endothelial migration (PEPITEM), a novel peptide, in alleviating experimental autoimmune encephalomyelitis (EAE), a mouse model for Multiple Sclerosis (MS).
Methods: Female C57BL/6 female mice were assigned to the control, untreated EAE, or PEPITEM group.
