PGRP-S (Tag7) is an innate immunity protein involved in the antimicrobial defense systems, both in insects and in mammals. We have previously shown that Tag7 specifically interacts with several proteins, including Hsp70 and the calcium binding protein S100A4 (Mts1), providing a number of novel cellular functions. Here we show that Tag7–Mts1 complex causes chemotactic migration of lymphocytes, with NK cells being a preferred target. Cells of either innate immunity (neutrophils and monocytes) or acquired immunity (CD4+ and CD8+ lymphocytes) can produce this complex, which confirms the close connection between components of the 2 branches of immune response. 相似文献

The present experiments were conducted to determine the stimulant effect of helium-neon laser on the postradiation recovery in irradiated uninjured skeletal muscle of rats aged 2-2.5. This was indicated by a restored ability of the muscle for posttraumatic regeneration. The both hind rat legs were exposed to local irradiation of 20 Gy and following laser therapy (8-9 procedures at 3 min each, impulsive or continuous one). Then both musculus gastrocnemius were cut across 30 days after irradiation. It was shown that laser therapy employed before injury of the irradiated muscle accelerated fibrin resorption and improved connective tissue, but slightly stimulated muscular tissue. Impulse laser therapy was more favourable for state of skin and healing of the skin wound after irradiation. 相似文献

In the present study the implantation of nonexposed muscle tissue to the site of injury in irradiated musculus gastrocnemius and following laser therapy were applied in order to stimulate this muscle's posttraumatic regeneration in old rats. It was shown that a far larger amount of functionally active muscle tissue was formed at the site of injury compared with rats received laser therapy alone or the ones which were only implanted nonexposed minced muscle tissue. The muscle tissue consisted of muscle fibers which originated from the grafted pieces of nonexposed skeletal muscle and the ones produced by myofibers of muscle stumps recovered after irradiation. The connective tissue developed more evenly. The formation of adipose tissue was not observed at the site of injury. Moreover, the skin wound healing and the hair growth were stimulated as well. 相似文献

The effect of muscle tissue alloplasty and laser radiation on the post-traumatic regeneration of skeletal muscles was studied. The implantation of an unirradiated minced allogenic muscle tissue into the area of trauma of a previously laser-irradiated muscle had a positive effect. The allogenic muscle tissue underwent active regeneration. The traumatized muscle fibers in the rat-recipient muscle grew into the alloplant. The implantation of a previously laser-irradiated muscle tissue into the area of trauma of an unirradiated muscle was less effective. The allogenic muscle tissue prevented the growth of rat-recipient myofibers and underwent lysis in general. The allotransplantation of a laser-irradiated muscle tissue into an x-irradiated (20 Gy) traumatized muscle increased the destruction of rat-recipient muscle tissue. 相似文献

It is known that regenerative capacity of skeletal muscles in guinea pigs is less than in rats. The guinea pig muscle regenerates are characterized by smaller muscle fibers and greater amounts of interstitial connective tissue. The present experiments were designed to stimulate the regenerative capacity of muscle tissue in adult guinea pigs, using tissue and laser therapy. It was shown that the minced muscle tissue implantation to the site of injury in m. gastrocnemius increased the quantity of regenerating muscle tissue. When the same operation was combined with following laser therapy the increase of muscle tissue was observed as well but not by far. At the same time laser therapy promoted noticeable acceleration of fibrin resorption, wound healing and regenerative modifications in implanted muscle fragments. Thus, the present methods stimulated relatively law regenerative capacity of guinea pig muscle tissue and promoted more qualitative recovery of injured area. 相似文献

Regeneration in murine musculus gastrocnemius was studied in animals aged 2-2.5. It was demonstrated that 20Cy irradiation caused the inhibition of necrosis resorption, suppressed the proliferative activity of muscular and connective tissues. Impulse laser therapy employed after irradiation of dissected musculus gastrocnemius potentiated fibrin resorption and markedly stimulated regeneration of muscular and connective tissues. Nonexposed disintegrated muscular tissue, when implanted to the site of injury produced a significant stimulating effect resulting in necrosis resorption, more pronounced than under laser therapy, and recovering the regenerative capacity of the exposed tissue. 相似文献
