Cystagon
In 2001, a drug used to treat cystinosis, a rare genetic disease that can cause kidney failure if not treated, was reported to be  useful in treating the infantile form of NCL. Preliminary results report the drug has completely cleared away storage material from the white blood cells of the first six patients, as well as slowing down the rapid neurodegeneration of infantile NCL.Currently, two drug trials are underway for infantile NCL, both using Cystagon. Gene therapy
A gene therapy trial using an adenoassociated virus vector called AAV2CUhCLN2 began in June 2004 in an attempt to treat the manifestations of late infantile NCL. The trial was conducted by Weill Medical College of Cornell University and sponsored by the Nathans Battle Foundation. In May 2008,  the gene therapy given to the recipients reportedly was "safe, and that, on average, it significantly slowed the diseases progression during the 18-month follow-up period" and "suggested that higher doses and a better delivery system may provide greater benefit".A second gene therapy trial for late infantile NCL using an adenoassociated virus derived from the rhesus macaque (a species of Old World monkey) called AAVrh.10 began in August 2010, and is once again being conducted by Weill Medical College of Cornell University.
Trichophyton is a genus of fungi, which includes the parasitic varieties that cause tinea, including athletes foot, ringworm, jock itch, and similar  infections of the nail, beard, skin and scalp. Trichophyton fungi are molds characterized by the development of both smooth-walled macro- and microconidia. Macroconidia are mostly borne laterally directly on the hyphae or on short pedicels, and are thin- or thick-walled, clavate to fusiform, and range from 4 to 8 by 8 to 50 μm in size. Macroconidia are few or absent in many species. Microconidia are spherical, pyriform to clavate or of irregular shape, and range from 2 to 3 by 2 to 4 μm in size. Species and their habitat preference
According to current classification, the genus includes anthropophilic and zoophilic species. Anthropophilic fungi prefer to infect humans. Zoophilic fungi prefer to infect animals other than humans. Humans and animals are natural reservoirs for parasitic or dermatophytic fungi. Other accepted species;

Mating and meiosis
Trichophyton mentagrophytes (Family Arthrodermataceae, Genus Trichophyton) is capable of both mating and meiosis. Effect on humans
The anthropophilic varieties cause forms of dermatophytosis, that is, fungal infection of the skin. They are keratinophilic: they feed on the keratin in nails, hair, and dead skin. Trichophyton concentricum causes "Malabar itch", a skin infection consisting of an eruption of a number of concentric rings of overlapping scales forming papulosquamous patches.Trichophyton rubrum and Trichophyton interdigitale cause athletes foot (tinea pedis), toenail fungal infections (a.k.a. tinea unguium, a.k.a. onychomycosis), crotch itch (a.k.a.
