Pellagra is a curable dietary illness that unchecked leads to dementia, diarrhoea, dermatitis and death due to lack of the precursors for NAD(H). In addition it caused a wide range of monosyndromic degenerative and functional neurological disorders as well as profound developmental, premature aging and metabolic syndromes. Pellagrins harbour many chronic infections including tuberculosis, yeasts and malaria, that may be symbionts supplying nicotinamide adenine dinucleotide {NAD(H)} when the diet is poor. Many common diseases and aging may be caused by electrogenic energy mismatches from lack of a timely supply of NAD(H) creating disturbed metabolic fields and "protonopathies". Initially these may present in compartments fronted by homeostatic corrections from chronic symbiotic infections to inflammatory disease, cancer and degenerative/autophagic diseases that can all release NAD(H).

Replicative capacity of a cell is strongly correlated with telomere length regulation. Aberrant lengthening or reduction in the length of telomeres can lead to health anomalies, such as cancer or premature aging. Telomerase is a master regulator for maintaining replicative potential in most eukaryotic cells. It does so by controlling telomere length at chromosome ends. Akin to cancer cells, most single-cell eukaryotic pathogens are highly proliferative and require persistent telomerase activity to maintain constant length of telomere and propagation within their host. Although telomerase is key to unlimited cellular proliferation in both cases, not much was known about the role of telomerase in human parasites (malaria, Trypanosoma, etc.) until recently. Since telomerase regulation is mediated via its own structural components, interactions with catalytic reverse transcriptase and several factors that can recruit and assemble telomerase to telomeres in a cell cycle-dependent manner, we compare and discuss here recent findings in telomerase biology in cancer, aging and parasitic diseases to give a broader perspective of telomerase function in human diseases.
