概括
口腔菌群的多样性随着艾滋病毒的进展而下降,而Candida在后期阶段显著增加. 某些真菌,如Debaryomyces和Talaromyces与艾滋病毒/艾滋病感染者免疫力改善相关.

- 人类免疫缺陷病毒 (HIV) 研究研究
- 微生物组研究 微生物组研究
背景情况:
- 口腔真菌感染在感染艾滋病毒/艾滋病的人群中很常见 (PLWHA).
- 关于艾滋病毒感染期间口腔真菌生物组变化的研究有限.
- 了解这些变化对于管理机会性感染至关重要.
研究的目的:
- 在PLWHA中分析口腔菌群多样性和组成.
- 为了比较艾滋病毒感染不同阶段的真菌生物组.
- 调查真菌生物和免疫标记物 (CD4+ T细胞计数,HIV病毒载量) 之间的相关性.
主要方法:
- 收集了63名艾滋病毒感染者 (0-3期) 和24名艾滋病毒阴性对照者的唾液样本.

Salivary Glands and Saliva
2.3K
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

Immunodeficiency Diseases
2.0K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
