The COVID-19 vaccine booster injection significantly increases the immunity of the macaque antibody response
American scientists wrote in the latest issue of the journal Science that their research on macaques showed that injecting a new crown vaccine booster injection can enhance the concentration of neutralizing antibodies in macaques and have a high level of protection. The latest findings support increasing vaccination rates for vaccine boosters in older adults, people with pre-existing health conditions, and people with high-risk exposure. The researchers also determined that the mRNA-1273 vaccine developed against the original coronavirus and the vaccine against the beta variant of the new coronavirus were equally capable of enhancing the antibody response and providing protection.

The "orphan recipient" is no longer alone! Scientists have found new signal receivers that regulate the central nervous system
For a long time, people think that bone is only an organ with a supporting and protective effect, and in the past 20 years, it has gradually been found that bone can also be used as a secretory organ, through the secretion of different bone-derived factors, it has an impact on various organs other than bone, and has regulatory functions on the central nervous system, immune system, energy metabolism and other aspects. Recently, Li Xiang's team at the Institute of Brain Cognition and Brain Diseases, Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences, discovered the key regulatory role of osteocalcin (OCN) on oligodendrocytes in the central nervous system, and for the first time defined a new receptor that mediates the new central function of osteocalcin- the G protein-coupled receptor (GPR37).
