ABSTRACT
Vascular cognitive impairment (VCI) is a clinical syndrome with impairment of at least one cognitive domain caused by vascular risk factors or cerebrovascular diseases, and its pathogenesis is not completely clear so far. Microglia are innate immune cells in the brain. They participate in many processes such as neuroinflammation, synaptic pruning, myelin regeneration, neurogenesis and connection. They are associated with the occurrence and development of various neurological diseases such as cerebral infarction, Alzheimer's disease, Parkinson's disease, and autism. Recent studies have shown that microglia play an important role in the development of VCI. This article reviews the role of microglia in VCI.
ABSTRACT
Gastric cancer is one of the most commonly seen malignant tumors,and is the fourth leading cause of morbidity and second leading cause of mortality among malignancies worldwide. The genesis of gastric cancer is the result of interaction between genetic and environmental factors,and is a multi-factor and multi-step carcinogenesis. As one of the most important members in the heat shock protein(HSP)family,HSP70 plays a molecular chaperone role,and is involved in body specific immunity and innate immunity. Studies have demonstrated that over expression of HSP70 often correlates with the genesis and development of gastric cancer. This article reviewed the advances in study on relationship between HSP70 and gastric cancer.
