Fungal cell surface protein and lectin

Fungal cell surface proteins and lectins are a diverse group of molecules embedded in the fungal cell wall that mediate critical interactions between the pathogen and the host environment [1]. These proteins include adhesins, such as the Agglutinin-like sequence (Als) family, which are essential for adhering to host tissues and forming biofilms [2]. Lectins on the fungal surface specifically recognize carbohydrate motifs on host cells, facilitating invasion and immune evasion [3]. Because these proteins are often unique to fungi and accessible on the exterior, they are primary targets for the development of antifungal vaccines and monoclonal antibodies [4]. For instance, the Als3 protein is a key target for the NDV-3A vaccine, which aims to prevent infection by blocking fungal adhesion [5]. Targeting these surface components offers a strategy to neutralize virulence without the high toxicity often associated with systemic small-molecule antifungals [6].

Mechanism of action for drugs targeting these molecules involves the inhibition of fungal adhesion to host cells, neutralization of virulence factors, and opsonization to facilitate immune-mediated clearance [4][6].
