Restoring immune balance with Tregitopes: A new approach to treating immunological disorders.

The induction of immunological tolerance is a promising strategy for managing autoimmune diseases, allergies, and transplant rejection. Tregitopes, a class of peptides, have emerged as potential agents for this purpose. They activate regulatory T cells, which are pivotal in reducing inflammation and promoting tolerance, by binding to MHC II molecules and facilitating their processing and presentation to Treg cells, thereby encouraging their proliferation.

Investigation of antibacterial and anticancer effects of novel niosomal formulated Persian Gulf Sea cucumber extracts.

Pharmaceutical companies worldwide are scrambling to develop new ways to combat cancer and microbiological pathogens. The goal of this research was to investigate the antibacterial, anticancer, and apoptosis effects of novel niosomal formulated Persian Gulf Sea cucumber extracts (SCEs). Sea cucumber methanolic extracts were prepared and encapsulated in niosome nanoparticles using thin-film hydration.

Allergen specific immunotherapy with plasmid DNA encoding OVA-immunodominant T cell epitope fused to Tregitope in a murine model of allergy.

Background: Peptide-based immunotherapy (PIT) was introduced as an attractive approach in allergen-specific immunotherapy (AIT). However, PIT clinical trials have shown variable results, and immune response to peptides is not precisely predictable. On the other hand, induction of antigen-specific tolerance may be augmented when allergens are combined with the regulatory T cell epitope (Tregitope).

Effects of Imipenem-containing Niosome nanoparticles against high prevalence methicillin-resistant Staphylococcus Epidermidis biofilm formed.

We aim to assess the antibacterial and anti-biofilm properties of Niosome-encapsulated Imipenem. After isolating Staphylococcus epidermidis isolates and determining their microbial sensitivity, their ability to form biofilms was examined using plate microtiter assay. Various formulations of Niosome-encapsulated Imipenem were prepared using the thin-film hydration method, Minimum Biofilm Inhibitory Concentration (MBIC) and Minimum Inhibitory Concentration (MIC) were determined, and biofilm genes expression was examined.

Targeting AMPK by Statins: A Potential Therapeutic Approach.

Statins are a group of lipid-lowering drugs that inhibit cholesterol biosynthesis and have anti-inflammatory, anti-tumor, and immunomodulatory properties. Several lines of evidence indicate that statins regulate multiple proteins associated with the regulation of differing cellular pathways. The 5'-adenosine monophosphate-activated protein kinase (AMPK) pathway plays an important role in metabolism homeostasis with effects on cellular processes including apoptosis and the inflammatory responses through several pathways.
