AnthraxToxinMechanismofAction
One of the key causes of anthrax virulence is the production of three specific factors by the gram-positive spore forming bacteria Bacillus anthracis. Even with successful antibiotic treatment, anthrax toxins can remain in the circulation and cause lethality. The toxins produced by anthrax bacteria are derived from three genes: lethal factor (LF), protective antigen (PA) and edema factor (EF). The entry of toxin into......阅读全文

SLC8A1基因突变因子与药物介绍
在心肌细胞中，Ca（2+）浓度在收缩时的高水平和舒张时的低水平之间交替收缩过程中ca（2+）浓度的增加主要是由于细胞内储存的ca（2+）释放所致。然而，一些Ca（2+）也通过肌膜（质膜）进入细胞在松弛过程中，ca（2+）被隔离在细胞内的储存中。为了防止细胞内存储物超载，必须从细胞中挤出穿过肌膜的Ca
