Autoimmune cross-targeting hypothesis
The layering of 2 different infections on one target triggering autoimmune disease. A viral infection marking the inside of the target then a bacterial, or fungal, or mycobacteria infection marking the outside.

How does tinea captis overlap with lichen planus? Just location? when the fungus causes loss of hair on the head?

tinea captis and trichophyton tonsurans

note that tinea captis is the specific type of alopecia (hair loss) that is caused by fungus?
Previously i had looked at alopecia as an autoimmune disease cross-targing of trichophyton and flaviviruses (west nile or hepatitis C)

Francis Peyton Rous' Co-carcinogenesis hypothesis: that a virus and a carcinogen together cause cancer. (1966 Nobel prize for HPV work) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2135410/
What I surmise from his hypothesis:
A virus enters a cell through a receptor, opens up and alters host DNA telomeres. The carcinogen inhibits the virus' polymerase because viral polymerases have stronger binding affinities than the host's.
Cancer cells can make unlimited copies because of the telomere modifications done by the virus.
There are DNA polymerases and RNA polymerases. Think of DNA as the cookbook and RNA as recipes...one polymerase copies the entire cookbook, one makes repairs, and one polymerase copies just a recipe.
If the viral polymerases are inhibited by the carcinogen instead of the host's polymerase then the cancer "stem" cell could be created. The host's polymerases have access to and can make unlimited copies.
