Parasite digestive protease (null)

Parasite digestive proteases are enzymes responsible for the hydrolysis of host proteins, primarily to provide essential amino acids for parasite growth, development, and reproduction. These proteases, comprising cysteine, serine, and aspartic families, perform critical roles in nutrient acquisition, tissue invasion, immune evasion, and overall pathogenicity. Their central roles in parasite biology and disease make them validated targets for drug and vaccine development, and a focus of extensive biochemical, structural, and therapeutic research[2][4][5][8]. Inhibitors that block digestive protease activity have demonstrated efficacy in preclinical models, and specific protease antigens are being trialed as vaccine candidates. Safety and specificity remain key therapeutic challenges owing to the broad conservation of protease families in both parasite and host[5][7].
