Autoimmune Disorders01:29

Autoimmune Disorders

683
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Genome-wide Association Studies-GWAS

14.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

概括

这项研究使用了门德尔的随机化来研究自身免疫性疾病 (AD) 和扩散性大B细胞淋巴瘤 (DLBCL) 之间的因果关系. 一些AD,包括Sjögren综合征和全身性红斑狼,显示了与DLBCL风险的潜在因果关系.
