In nature, the majority of chemical reactions, biological responses, and regulatory processes are modulated in some part by specific amino acid sequences. The transfer of these interactive sequences and the biological activities they induce to short, stable, and readily synthesized peptides has created a diverse new field of modulating molecules applicable to dermatology and skin care industrie...

Background: Opioids are amongst the most common abused drugs. Pathologic studies on opioid abuse are limited since the evaluation of inflammation and regeneration in brain tissue is not as simple as other tissues of the body. Thus, the present study aimed to determine the relationship between the dependence on morphine and inflammatory and regenerative processes. Methods: In this experimental s...

The attenuation of ancestral pro-regenerative pathways may explain why humans do not efficiently regenerate damaged organs. Vertebrate lineages that exhibit robust regeneration, including the teleost zebrafish, provide insights into the maintenance of adult regenerative capacity. Using established models of spinal cord, heart, and retina regeneration, we discovered that zebrafish Treg-like (zTr...

Periodontitis is one of the most common osteolytic inflammatory diseases in humans. Formation a periodontal bacteria-associated biofilm thought to be trigger for development periodontitis, but it not believed sufficient by itself sustain disease, as compromise host immune response critical tissue breakdown and disease progression. Macrophages play an important role both during initiation resolu...

Skeletal muscle has an ability to regenerate in response to injury due to the presence of satellite cells. Injury in skeletal muscle causes infiltration of pro-inflammatory macrophages (M1 macrophages) to remove necrotic myofibers, followed by their differentiation into anti-inflammatory macrophages (M2 macrophages) to terminate the inflammation. Since both M1 and M2 macrophages play important ...

PURPOSE Emphysema is an irreversible disease that is characterized by destruction of lung tissue as a result of inflammation caused by smoking. Resolvin D1 (RvD1), derived from docosahexaenoic acid, is a novel lipid that resolves inflammation. The present study tested whether RvD1 prevents smoking-induced emphysema and promotes lung tissue regeneration. MATERIALS AND METHODS C57BL/6 mice, 8 w...

The vitality of the pulp is fundamental to the functional life of the tooth. For this aim, active and living biomaterials are required to avoid the current drastic treatment, which is the removal of all the cellular and molecular content regardless of its regenerative potential. The regeneration of the pulp tissue is the dream of many generations of dental surgeons and will revolutionize clinic...

INTRODUCTION Surgical resection is the gold standard in treatment of hepatic malignancies, giving the patient the best chance to be cured. The liver has a unique capacity to regenerate. However, an inflammatory response occurs during resection, in part mediated by Kupffer cells, that influences the speed of regeneration. The aim of this study was to investigate the effect of a Kupffer cell targ...

BACKGROUND IL-6 is a pleiotropic cytokine that modulates inflammatory responses and plays critical roles in muscle maintenance and remodeling. In the mouse model (mdx) of Duchenne Muscular Dystrophy, IL-6 and muscle inflammation are elevated, which is believed to contribute to the chronic inflammation and failure of muscle regeneration in DMD. The purpose of the current study was to examine the...

A healthy diet rich in fruits and vegetables is an important part of a healthy lifestyle. Whereas epidemiological data sometimes fail to provide proof of this concept, molecular evidence is accumulating that clearly shows both preventive as well as therapeutic effects of compounds from natural origins. in the paper of Guido Kroemer's group about pro-autophagic polyphenols and their inhibitory e...
