Abstract

, along with several non-albicans species, comprise a prominent fungal pathogen in humans, leading to candidiasis in various organs. The global impact of candidiasis in terms of disease burden, suffering, and fatalities is alarmingly high, making it a pressing global healthcare concern. Current treatment options rely on antifungal drugs such as azoles, polyenes, and echinocandins but are delimited due to the emergence of drug-resistant strains and associated adverse effects. The current review highlights the striking absence of a licensed antifungal vaccine for human use and the urgent need to shift our focus toward developing an anti-Candida vaccine. A number of factors affect the development of vaccines against fungal infections, including the host, intraspecies and interspecies antigenic variations, and hence, a lack of commercial interest. In addition, individuals with a high risk of fungal infection tend to be immunocompromised, so they are less likely to respond to inactivated or subunit whole organisms. Therefore, it is pertinent to discover newer and novel alternative strategies to develop safe and effective vaccines against fungal infections. This review article provides an overview of current vaccination strategies (live attenuated, whole-cell killed, subunit, conjugate, and oral vaccine), including their preclinical and clinical data on efficacy and safety. We also discuss the mechanisms of immune protection against candidiasis, including the role of innate and adaptive immunity and potential biomarkers of protection. Challenges, solutions, and future directions in vaccine development, namely, exploring novel adjuvants, harnessing the trained immunity, and utilizing immunoinformatics approaches for vaccine design and development, are also discussed. This review concludes with a summary of key findings, their implications for clinical practice and public health, and a call to action for continued investment in candidiasis vaccine research.

摘要

与几种非白色念珠菌属物种一起,构成了人类中一种重要的真菌病原体,可导致各个器官的念珠菌病。念珠菌病在疾病负担、痛苦和死亡方面的全球影响高得惊人,使其成为一个紧迫的全球医疗保健问题。目前的治疗选择依赖于抗真菌药物,如唑类、多烯类和棘白菌素类,但由于耐药菌株的出现和相关的不良反应而受到限制。本综述强调了目前仍缺乏用于人类的获得许可的抗真菌疫苗,以及迫切需要将重点转向开发抗念珠菌疫苗。许多因素影响抗真菌感染疫苗的开发,包括宿主、种内和种间抗原变异,因此缺乏商业利益。此外,真菌感染风险高的个体往往免疫功能低下,因此他们对灭活或亚单位全生物体的反应较小。因此,有必要发现更新颖的替代策略来开发针对真菌感染的安全有效的疫苗。这篇综述文章概述了当前的疫苗接种策略(减毒活疫苗、全细胞灭活疫苗、亚单位疫苗、结合疫苗和口服疫苗),包括它们在疗效和安全性方面的临床前和临床数据。我们还讨论了针对念珠菌病的免疫保护机制,包括固有免疫和适应性免疫的作用以及潜在的保护生物标志物。还讨论了疫苗开发中的挑战、解决方案和未来方向,即探索新型佐剂、利用训练有素的免疫以及利用免疫信息学方法进行疫苗设计和开发。本综述最后总结了主要发现、它们对临床实践和公共卫生的影响,并呼吁继续投资念珠菌病疫苗研究。
