In addition to making great progress in these important areas, small peptide drugs have also made some progress in many other areas. For example, Stiernberg and others found that a synthetic peptide (TP508) peptide can promote the regeneration of blood vessels in the wound, accelerating the healing of deep wounds in the skin. Pfister et al. found that a small peptide (RTR) 4 can prevent alkali damage to the endomecomy of the inflammatory cells, inhibit the inflammatory response. Carron et al. confirmed that the two synthetic peptides it screened inhibited the reabsorption of bone mass by bone-breaking cells.
