1 In latent infection- retroviral genome is present but is not transcribing viral genome or mRNA for structural proteins. Distinguished by qPCR (DNA) and qRT-PCR (RNA) Retroviral Life Cycle: Latent vs. Active infection In latent infection- retroviral genome is present but is not transcribing viral genome or mRNA for structural proteins. Distinguished by qPCR (DNA) and qRT-PCR (RNA)

2 Not a mouse contaminant XMRV is a new human retrovirus Not prostate cancer XMRV Not a mouse contaminant XMRV is a new human retrovirus Not prostate cancer XMRV Phylogenetic analysis revealed that XMRV isolates from prostate cancer and CFS form a distinct branch within non ecotronic MLVs

4 CFS Study Cohort Reported in Science: Study cohort from the WPI national repository. Repository samples include samples from NV, CA, OR, FL, NC and NY as well as international CFS patients. Repository inclusion criteria: – CFS diagnosis, regardless of severity – years of age Study characteristic: – 67% women, reflecting gender incidence of CFS – Mean age: 55 – 320 control samples from same geographic locations

5 Questions What cell types are infected? How is XMRV transmitted? Do infected individuals make an immune response? What are the interactions between XMRV and the innate immune system? Does XMRV infection alter the risk of cancer development in CFS? Can we develop immune based therapies for CFS based on XMRV?
