Neuroinvasion by human respiratory coronaviruses.
Human coronaviruses (HCoV) cause common colds but can also infect neural cell cultures. To provide definitive experimental evidence for the neurotropism and neuroinvasion of HCoV and its possible association with multiple sclerosis (MS), we have performed an extensive search and characterization of HCoV RNA in a large panel of human brain autopsy samples. Very stringent reverse transcription-PC...
متن کاملA Route for Prion Neuroinvasion
The astonishing recognition that self-propagating changes in protein structure may be at the basis of spongiform encephalopathies is changing our views of transmissible diseases. Infectious agents consisting of abnormally folded proteins (i.e., the prion) can propagate in host organisms using previously unrecognized routes and invade the brain after a dangerous liaison with the immune system. T...
متن کاملPeripheral B Lymphocytes
Background: Based on the hypothesis that IgGs are potent tolerogens and that immature lymphohematopoietic antigen-presenting cells (APC), and even mature peripheral B cells, may be effective APC for tolerance induction, we designed an immunoglobulin fusion protein retroviral expression vector to test the role of B cells in a novel gene therapy strategy for the transfer of immune tolerance. Meth...
متن کاملOntogeny of B Lymphocytes
Many bursa-equivalent (B) lymphocytes of adult mice bear surface Ig and receptors for C3. The frequency of Ig-bearing cells increases rapidly immediately after birth, but these cells lack complement (C) receptors. Lymphocytes bearing C receptors are not found in the spleens of BALB/c, DBA/2, and C57BL/6 mice until 2 wk of age and do not attain substantial numbers until 3-4 wk of age. In AKR mic...
متن کاملDifferential DNA methylation profiles of human B lymphocytes and Epstein-Barr virus-immortalized B lymphocytes.
Objective This study aimed to comprehensively assess Epstein-Barr virus (EBV)-induced methylation alterations of B cell across whole genome. Methods We compared DNA methylation patterns of primary B cells and corresponding lymphoblastoid cell lines (LCLs) from eight participants. The genome-wide DNA methylation profiles were compared at over 850,000 genome-wide methylation sites. Results DN...
