Extracellular vesicles like exosomes are important therapeutic tactics for treating COVID -19. By utilizing convalescent plasma derived exosomes (CP) from COVID-19 recovered persistence could accelerate the treatment strategies in the current state of affairs. Adequate literature has shown that administering the exosome to the in vivo system could be beneficial and could target the pathogens in an effective and precise manner. In this hypothesis we highlight the CP instead of convalescent plasma (CP), perhaps to dispense of exosomes are gratified and it's more effectively acquired immune response conferral through antibodies. COVID-19 convalescent plasma has billions of exosomes and it has aptitudes to carry molecular constituents like proteins, lipids, RNA and DNA, etc. Moreover, exosomes are capable of recognizing antigens with adequate sensitivity and specificity. Many of these derivatives could trigger an immune modulation into the cells and act as an epigenetic inheritor response to target pathogens through RNAs. COIVID-19 resistance activated plasma-derived exosomes are either responsible for the effects of plasma beyond the contained immune antibodies or could be inhibitory. The proposed hypothesis suggests that preselecting the plasma-derived antibodies and RNAs merged exosomes would be an optimized therapeutic tactic for COVID-19 patients. We suggest that, the CP has a multi-potential effect for treatment efficacy by acting as immunotherapeutic, drug carrier, and diagnostic target with noncoding genetic materials as a biomarker.
像外泌体这样的细胞外囊泡是治疗新冠肺炎的重要治疗策略。通过利用来自新冠肺炎康复者的恢复期血浆衍生外泌体(CP),可以在当前情况下加速治疗策略。大量文献表明,将外泌体应用于体内系统可能有益,并且可以有效且精确地靶向病原体。在本假说中,我们强调的是CP而非恢复期血浆,或许是因为外泌体令人满意,并且通过抗体能更有效地获得免疫反应。新冠肺炎恢复期血浆含有数十亿个外泌体,并且有能力携带蛋白质、脂质、RNA和DNA等分子成分。此外,外泌体能够以足够的敏感性和特异性识别抗原。这些衍生物中的许多能够触发细胞内的免疫调节,并通过RNA作为对靶向病原体的表观遗传继承反应。新冠病毒抗性激活的血浆衍生外泌体要么是血浆中所含免疫抗体之外的效应的原因,要么可能具有抑制作用。所提出的假说表明,预先选择血浆衍生抗体和RNA融合的外泌体将是新冠肺炎患者的一种优化治疗策略。我们认为,CP通过作为免疫治疗剂、药物载体以及以非编码遗传物质作为生物标志物的诊断靶点,对治疗效果具有多方面的潜在作用。
