Abstract

Several vaccine candidates have been introduced for immunization against Pseudomonas aeruginosa strains. Despite extensive efforts in recent decades, there is no accurate immunogenic candidate against this pathogen in the market yet. Due to the rapid increase in several drug-resistant strains, P. aeruginosa has caused various health concerns worldwide. It encodes many specific virulence features, which can be used as an appropriate vaccine candidate. The primary stage of the pathogenesis of P. aeruginosa is the expression of many dynamic adhesive molecules, such as type IV pili (T4P), which acts as a principal colonization factor. It has been confirmed that three different subtypes of T4P, including type IVa (T4aP), type IVb (T4bP) and tight adherence (Tad) pili are expressed by P. aeruginosa. The IVa fimbriae type is almost the main cause of challenges to design an effective pili based-immunotherapy method. Nevertheless, in terms of heterogeneity, variability and hidden conserved binding site of T4aP, this attitude has been remained controversial and there is no permitted human study based on IVa pilin commercially. The engineered synthetic peptide-based vaccines are highly talented to mimic the target. In this research, for t...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
