Escaping High Viral Load Exhaustion
Deletion, anergy, and a spectrum of functional impairments can affect virus-specific CD8 cells in chronic viral infections. Here we characterize a low frequency population of CD8 cells present in chronic hepatitis B virus (HBV) infection which survive in the face of a high quantity of viral antigen. Although they do not appear to exert immunological pressure in vivo, these CD8 cells are not cla...

Deletion, anergy, and a spectrum of functional impairments can affect virus-specific CD8 cells in chronic viral infections. Here we characterize a low frequency population of CD8 cells present in chronic hepatitis B virus (HBV) infection which survive in the face of a high quantity of viral antigen.

متن کاملHigh antigen levels are the cause of T cell exhaustion during chronic viral infection.
Many persistent viral infections induce dysfunctional T cell responses. Although a negative correlation exists between viral load and T cell responses during chronic infection, it is not known whether high antigen levels are the cause or just the consequence of T cell exhaustion. Furthermore, it is unclear what role antigen presentation by bone-marrow (BM) derived versus infected parenchymal ce...
متن کاملAssessment of HTLV-I proviral load, HIV viral load and CD4 T cell count in infected subjects; with an emphasis on viral replication in co-infection
Objective(s): HTLV-I and HIV virus quantification is an important marker for assessment of virus activities. Since there is a direct relationship between the number of virus and disease progression, HTLV- I and HIV co-infection might have an influence on the development of viral associated diseases, thus, viral replication of these viruses and co-infection were evaluated. Materials and...
متن کاملThe relation between symptoms, viral load, and viral load set point in primary HIV infection.
OBJECTIVES To examine the relation between symptoms, initial viral load, and viral load set point in primary HIV infection (PHI). DESIGN Prospective cohort of patients with preseroconversion or recent seroconversion HIV infection (typically <60 days) in San Francisco. METHODS Subjects were questioned about 21 potential PHI symptoms at enrollment and were subsequently followed with viral loa...
