The French Pasteur Institute announced today that the Institute and Portuguese researchers have collaborated to find a key protein that can affect the human immune system on Streptococcus type B, which is important for the development of anti-Streptococcus vaccine . The study was published today in the Journal of Immunology. Streptococcus type B is a bacterium that exists in the intestinal tract and urogenital system. Streptococcus type B exists in the vagina or intestine of about 10% -35% of healthy women. Under normal circumstances, Streptococcus type B is harmless to adults, but it will have a significant impact or even harm to newborns. Most of the neonatal type B streptococcal infections come from the vertical infection of the mother. Once infected, the fetus in the mother's body to the neonate 3 months after birth may be morbid, especially for newborns with low immunity, B Streptococcus type B is very infectious and can cause bacterial sepsis, meningitis, and bacterial pneumonia. Therefore, Streptococcus type B is known as the number one killer of neonatal sepsis. At present, despite the use of antibiotics and other means, many newborns worldwide die of Streptococcus B infection every year. More seriously, 25% -50% of cured children will have neurological sequelae. Researchers from the Pasteur Institute and the Portuguese Academy of Biomedical Sciences have discovered a protein secreted by Streptococcus type B, GAPDH. This protein can promote the production of IL-10, a lymphokine in the immune system, and The consequence of increased IL-10 lymphokine is to reduce the immune system's resistance, which eventually leads to easy infection by various pathogens. In addition, the researchers also proved through animal experiments that mice with IL-10 lymphokine deficiency were significantly more resistant to Streptococcus type B than normal mice. Therefore, the researchers believe that GAPDH protein can be used to develop immune proteins against Streptococcus type B, and pre-immunization experiments in mice have also shown that GAPDH protein has the function of fighting against Streptococcus type B infection. At present, researchers have begun to study the vaccine against Streptococcus type B based on GAPDH protein. Strapping machines use strapping straps to strap products or packages, and then tighten and combine the two ends by hot-melt hot-melt bonding. The function of the packing machine is to reinforce the packaged items, so that the items will not be scattered due to the loose binding during the transportation and storage, and they should also be bundled neatly and beautifully.
