Peptides – A Widely Used Therapeutic Molecule

Peptides are long, chain-like proteins, composed of amino acids and other structural building blocks of proteins. The word ‘pep’ is derived from the Greek term, meaning a grain or the end part of a grain. Peptides have been a major area of research in recent years because they have the ability to penetrate deeply through many layers of tissue in order to reach the target protein. They therefore offer a potent source of medical treatments and therapeutic outcomes, ranging from the successful treatment of infectious diseases and cancers to the regeneration of healthy tissue in injured organs.

Peptides have the ability to stimulate multiple immune system functions such as antigen-dependent cell response, stimulation of blood clotting, regulation of inflammatory processes, protection of micro-circulatory functions, regulation of immunity and wound healing. Peptides serve as signal cells and receptor cells for several immune and inflammatory responses such as: macrophage and T-cell response, regulation of interferon gamma produced by B cells, regulation of interleukin gene expression, recognition and localization of microbial antigens, regulation of biological response, recruitment of micro-influences like biochemical and genetic immunity, regulation of transcription factors responsible for development of target genes involved in development of immunity, regulation of inflammatory processes, recruitment of intracellular and extranial pathogens, regulation of antioxidant enzyme activity, and many others. The primary role of peptides is to strengthen the defense of the body from invading microorganisms and chemicals. Peptides act as chemical sensors, eliciting protective responses from the targeted organisms.
Peptides are widely used in many areas of therapeutic medicine because of their multiple beneficial effects on health. Peptides can be absorbed into the human body, carried by the bloodstream and moved throughout the body via natural mechanisms. Peptides can act on the nervous system, blood vessel walls, muscles, organs, tissues, and other biological tissues. Peptides have a wide range of action in the body, acting on various functions by different means.
