is inherently susceptible to arboviruses. The geographical expansion of this vector host species has led to the persistence of Dengue, Zika, and Chikungunya human infections. These viruses take advantage of the mosquito's cell to create an environment conducive for their growth. Arboviral infection triggers transcriptomic and protein dysregulation in and in effect, host antiviral mechanisms are compromised. Currently, there are no existing vaccines able to protect human hosts from these infections and thus, vector control strategies such as mass release program is regarded as a viable option. Considerable evidence demonstrates how the presence of interferes with arboviruses by decreasing host cytoskeletal proteins and lipids essential for arboviral infection. Also, strengthens host immunity, cellular regeneration and causes the expression of microRNAs which could potentially be involved in virus inhibition. However, variation in the magnitude of 's pathogen blocking effect that is not due to the endosymbiont's density has been recently reported. Furthermore, the cellular mechanisms involved in this phenotype differs depending on strain and host species. This prompts the need to explore the cellular interactions between -arboviruses- and how different strains overall affect the mosquito's cell. Understanding what happens at the cellular and molecular level will provide evidence on the sustainability of vector control.
按蚊属极易感染虫媒病毒。这种媒介宿主物种的地理扩张导致登革热、寨卡和基孔肯雅热等人类感染的持续存在。这些病毒利用蚊子的细胞创造一个有利于它们生长的环境。虫媒病毒感染会触发 和 的转录组和蛋白质失调,实际上,宿主抗病毒机制受到损害。目前,没有现有的疫苗能够保护人类宿主免受这些感染,因此,控制蚊虫的策略,如大规模释放计划,被认为是一种可行的选择。大量证据表明, 通过减少宿主细胞骨架蛋白和脂质来干扰虫媒病毒,这些蛋白和脂质对虫媒病毒感染至关重要。此外, 还能增强宿主的免疫力、细胞再生,并导致微 RNA 的表达,这些微 RNA 可能参与病毒抑制。然而,最近有报道称, 对病原体的阻断作用的大小变化并非归因于共生体的密度。此外,这种表型所涉及的细胞机制因 株和宿主物种而异。这促使人们需要探索 - 蚊 - 和不同 株如何影响蚊子细胞之间的细胞相互作用。了解细胞和分子水平上发生的情况将为 蚊虫控制的可持续性提供证据。
