The comparison revealed that humans have their own unique version of the gene for CD33, a receptor in immune cells that plays an important role in binding to a type of sugar called sialic acid. Human cells are coated with it and it helps immune cells "recognize" other cells and not attack them.,"Somewhere along the evolutionary line, humans picked up an additional mutated form of CD33 that is missing the sugar-binding site," the authors said. "The mutated receptor no longer reacts to sialic acids on damaged cells and plaques, allowing the microglia to break them down. Indeed, higher levels of this CD33 variant were independently found to be protective against late-onset Alzheimer's.",It would seem that CD33 was selected by evolution for its survival advantages, later making sure that humans were able to have big families that represent several generations. All of this, albeit indirectly, thanks to gonorrhea.。    每经头条（nbdtoutiao）——金价直逼1000元/克大关，深圳水贝顾客络绎不绝，记者实探：有人一单买走1斤多黄金！白银也卖爆，有商家几天卖了几十公斤     （记者陈鹏程）     免责声明：本文内容与数据仅供参考，不构成投资建议，使用前请核实。
