Reduced levels of reactive oxygen species correlate with inhibition of apoptosis, rise in thioredoxin expression and increased bovine leukemia virus proviral loads [PDF]

Retrovirology, 2009
Background Bovine Leukemia virus (BLV) is a deltaretrovirus that induces lymphoproliferation and leukemia in ruminants. In ex vivo cultures of B lymphocytes isolated from BLV-infected sheep show that spontaneous apoptosis is reduced.

Expression of integrins β1, α4 and cell adhesion molecule ICAM-1 in the presence of sodium deoxyribonucleate with ferrum complex (DNA-Na-Fe) by MT-4 cells transformed by human T-lymphotropic virus type 1 (Retroviridae: Orthoretrovirinae: Deltaretrovirus: Human T-lymphotropic virus type 1)

Problems of Virology, 2021
Introduction. The important role of integrins (IG) in the initiation and development of cancer processes makes these structures convenient targets for the development of immunomodulatory therapeutic drugs that have an effect directly on these molecules.
