About this listen
Understanding fungal cellular architecture reveals why certain structures serve as effective drug targets while others prove unsuitable for selective toxicity.
Fungal cells share eukaryotic features with humans—membrane-bound organelles, nucleus with linear chromosomes, mitochondria—but possess critical differences exploitable therapeutically. The fungal cell wall, composed of chitin, β-glucans, and mannoproteins, creates structural rigidity absent in animal cells. This unique structure makes cell wall synthesis an ideal drug target—disrupting it harms fungi without affecting human cells lacking walls.
Simply said: Antifungals target fungal-specific structures—ergosterol in membranes, β-glucan in cell walls, and unique ergosterol synthesis enzymes—exploiting differences from human cells.
Memory Trick: "Ergosterol not cholesterol, Glucan not in humans"—these fungal-specific structures provide selective drug targets.
