Targeting Toll-Like Receptors: a step closer to effective recombinant subunit vaccines
نویسنده
چکیده
The control and prevention of infectious diseases through immunization is one of the greatest achievements of modern medicine since Edward Jenner pioneered smallpox vaccination. However, future challenges in improving the efficacy of existing vaccines, development of new prophylactic vaccines for infectious diseases and therapeutic immunization for noninfectious diseases require extensive work to reveal key components of the molecular immune mechanism involved. Successful activation of innate immune response is a prerequisite for successful immunization and activation of adaptive immunity. Innate immune system comprises numerous evolutionary conserved pattern-recognition receptors (PRRs) that bind structural components shared by many pathogens. Upon binding the ligand, cascade reaction results in de novo gene expression required for immediate immune response by innate immunity and the activation of specific immune response mediated by the humoral and cellular mediators. Appropriate selection of specific pattern-recognition receptor ligands (adjuvants) enables formulation of the next generation vaccines, with controlled minimal adverse symptoms and efficient adaptive immunity development.

TLR, NLR and other modulators as infectious disease vaccine adjuvants
Vaccines based on attenuated or killed viruses and bacteria are highly effective in preventing infection with a range of pathogens, but can have safety issues. Therefore, there is a move towards subunit vaccines based on recombinant proteins or naked DNA. However, protein subunit vaccines are typically poorly immunogenic when administered alone and therefore require co-administration with adjuv...

Background: The pathogenesis of inflammatory bowel disease is complex and multifactorial. Studies have led to the current concept that Toll-like receptors represent key mediators of innate host defense in the intestine, and they are involved in maintaining mucosal as well as commensal homeostasis. We studied the possibility of simvastatin and antagonist of receptors of interleukin-1 for pharmac...

Foot-and-mouth disease (FMD) is a contagious viral disease of livestock with significant economic effect. It is prevalent in various regions of Asia, Africa, and South America. The causative agent of this disease is called foot-and-mouth disease virus (FMDV), which is a member of Aphthovirus genus. Vaccination is an effective technique to prevent the complications of FMD and to eradicate the di...
