Treatment modalities for systemic mycoses are still limited. Currently, the main antifungal therapeutics include polyenes, azoles, and echinocandins. However, even in the setting of appropriate administration of antifungals, mortality rates remain unacceptably high. Moreover, antifungal therapy is expensive, treatment periods can range from weeks to years, and toxicity is also a serious concern. In recent years, the increased number of immunocompromised individuals has contributed to the high global incidence of systemic fungal infections. Given the high morbidity and mortality rates, the complexity of treatment strategies, drug toxicity, and the worldwide burden of disease, there is a need for new and efficient therapeutic means to combat invasive mycoses. One promising avenue that is actively being pursued is nanotechnology, to develop new antifungal therapies and efficient vaccines, since it allows for a targeted delivery of drugs and antigens, which can reduce toxicity and treatment costs. The goal of this review is to discuss studies using nanoparticles to develop new therapeutic options, including vaccination methods, to combat systemic mycoses caused by sp., sp., sp., sp., sp., and sp., in addition to providing important information on the use of different types of nanoparticles, nanocarriers and their corresponding mechanisms of action.
治疗全身性真菌感染的方法仍然有限。目前,主要的抗真菌治疗药物包括多烯类、唑类和棘白菌素类。然而,即使在适当使用抗真菌药物的情况下,死亡率仍然高得令人无法接受。此外,抗真菌治疗费用昂贵,治疗期可能从数周延长至数年,且毒性也是一个严重的问题。近年来,免疫功能低下人群的增加导致全球系统性真菌感染的发病率居高不下。鉴于高发病率和死亡率、治疗策略的复杂性、药物毒性以及全球疾病负担,需要新的、有效的治疗手段来对抗侵袭性真菌感染。纳米技术是一种很有前途的方法,它被积极用于开发新的抗真菌疗法和有效的疫苗,因为它可以实现药物和抗原的靶向递送,从而降低毒性和治疗成本。本综述的目的是讨论使用纳米颗粒开发新的治疗选择,包括疫苗接种方法,以对抗由 、 、 、 、 、 等引起的全身性真菌感染,并提供有关不同类型的纳米颗粒、纳米载体及其相应作用机制的重要信息。
