Isoprenoids, a diverse group of compounds derived from the five-carbon building units isopentenyl diphosphate (IPP) and its isomer dimethylallyl diphosphate (DMAPP), are essential for survival in all organisms. Animals synthesize their isoprenoids from mevalonic acid (MVA), whereas most pathogenic bacteria and the malaria parasites utilize a completely different pathway for IPP and DMAPP synthesis, the methylerythritol phosphate (MEP) pathway. Plants use both pathways for the synthesis of isoprenoid precursors. The recent elucidation of the MEP pathway has opened the possibility to develop new strategies against microbial pathogens. Novel immunotherapeutic agents can be developed based on the MEP pathway intermediates known to activate the proliferation of human V-delta-9V-gamma-2 T-cells after infection by many pathogenic bacteria and protozoa. Moreover, the design of specific inhibitors of …
