皮肤病学皮肤病学
微生物组研究微生物组研究
自免疫性疾病的发病因子发病因子

背景情况:

Vitiligo 是一种自身免疫性皮肤疾病,在全球影响0.4-2%,未知触发因素.
人们越来越认识到肠道微生物群在免疫介导疾病中的作用.
这项研究调查了印度白风患者的肠道微生物组差异,包括那些有家族病史的人.

研究的目的:

分析和比较白风患者和健康对照人群之间的肠道微生物组合.
确定与白风相关的特定微生物种群和功能途径.
探索与其他自身免疫性疾病的潜在共同点.

Bacterial Flora of the Large Intestine

Bacterial Flora of the Large Intestine

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
