载体传播疾病的研究研究.
生物化学生化学

背景情况:

埃及蚊子 (Aedes aegypti) 传播着登革热,寨卡和奇孔古尼亚病毒.
蚊子的血液粉消化依赖于蛋白酶,素类活性占主导地位.
其他蛋白质酶的特定作用,如 chymotrypsin,在 Ae. 埃及人的消化过程还不太清楚.

研究的目的:

描述AE的活动概况和作用. 在血液消化过程中,Aegypti chymotrypsin (AaCHYMO).
调查控制AaCHYMO表达和活动的监管机制.
评估AaCHYMO作为新型载体控制策略的潜在目标.

主要方法:

在Ae.中对AaCHYMO和ecdysone受体 (EcR) 的基因敲除. 埃及. 埃及.
测试以测量中肠提取物中基米托里普辛类活性.
在体外光和血液蛋白质消化测试.
在淘汰蚊子中的生育能力评估.

主要成果:

Knockdown of AaCHYMO显著降低了血液养蚊子中类似基米托里普辛的活性.
在实验室中,AaCHYMO表现出特定的基质偏好.
击倒阿奇莫并没有影响蚊子的生育能力.
击倒EcR降低了Aachymo的表达和活性,这表明其具有调节作用.

结论:

Diversity of Protists I

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Giardiasis

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
