A new study suggests that appendectomy can reduce risk
Researchers have found that their appendix tissue has protein clusters similar to those observed in the brains of Parkinson's disease patients. This discovery suggests that the appendix plays a role in the early stages of this disease by aggregating these same proteins. These proteins contribute to Parkinson's disease in some way, so appendectomy may prevent their harmful activity.

According to the World Health Organization, 90% of people worldwide breathe polluted air every day. Air pollution causes 7 million premature deaths annually due to diseases such as cancer, stroke, heart disease, and lung disease. 90% of premature deaths occur in low - to middle-income countries with high emissions of industrial, transportation, and agricultural pollutants.

Cancer cells are very "cunning", they will use immune checkpoints to conceal their "bad person identity" - the proteins expressed on the surface of tumor cells will bind to the proteins on the surface of T cells, sending a signal to the immune system to "own people, don't kill me", thus avoiding the detection and attack of immune cells.Based on this principle, scientists have developed antibodies that block binding, namely immune checkpoint inhibitors, to achieve anti-cancer goals by releasing T cells. So far, the FDA has approved six immune checkpoint inhibitors targeting pathways, suitable for various cancers such as melanoma, non-small cell lung cancer, and renal cell carcinoma.

Recently, a landmark study on neural cells was published, in which researchers claimed to have discovered that brain neurons can modify their own DNA on their own. For a long time, the biomedical community has believed that human somatic DNA is fixed. According to Science, the discovery that "brain cells can modify their own DNA" has been evaluated as "possibly one of the major discoveries in the field of molecular biology in recent years". Researchers analyzed the donated brains of 6 healthy elderly individuals and 7 non secondary Alzheimer's disease patients and found that patients with Alzheimer's disease carry six times more APP variant gene varieties in their neuronal cells than the general population. Therefore, researchers speculate that the ability of brain cells to modify DNA on their own may contribute to the development of Alzheimer's disease.
