A biology project H. pylori
Recently, our biology teacher gave us a project to take a deeper look at the H. pylori. It is a bacterium that causes gastric cancer and gastric ulcer. The reason is that it can secrete three types of chemical CagA, VacA and Urease. CagA can activate IL-8 and cause inflammation and finally cause gastric cancer. VacA can cause apoptosis and trigger cell damage and T cell inhibition. Urease can trigger gastric ulcer and eventually lead to gastric cancer.
Although these complex mechanism made me upset, these are important in clinical treatment for a doctor. So I have to remember all these processes and teacher will give us a final exam.
