Cellular basis of persistent lymphocytosis in cattle infected with bovine leukemia virus.
Peripheral blood lymphocytes from 14 cattle infected with the bovine leukemia virus (BLV) and 14 BLV-free cattle were examined by the membrane immunofluorescent antibody technique to detect surface immunoglobulin (S-Ig) and by the erythrocyte-antibody-complement (EAC) rosette test for the detection of complement receptors. Direct comparisons of the percentages of S-Ig-bearing cells and EAC rose...
متن کاملGlucocorticoid receptors in peripheral blood lymphocytes from bovine leukemia virus-infected cows with persistent lymphocytosis.
Bovine leukemia virus-infected cows with persistent lymphocytosis have an expanded population of B-lymphocytes in the peripheral blood that is sensitive to glucocorticoids in vitro and in vivo. We examined peripheral blood lymphocytes from cows with persistent lymphocytosis for the presence of specific glucocorticoid receptors. Steroid binding in intact cells was determined by a whole cell comp...
متن کاملPersistent bovine viral diarrhea virus (BVDV) infection in cattle herds
Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...
متن کاملBovine immunodeficiency virus and bovine leukemia virus and their mixed infection in Iranian Holstein cattle.
INTRODUCTION Bovine immunodeficiency virus (BIV) and bovine leukemia virus (BLV) have worldwide distributions, but their prevalences in Iran are unknown. We investigated the presence of infections in Iranian Holstein cattle and determined changes in hematological values for infected animals. METHODOLOGY Nested PCR was used on blood samples from 143 animals Holstein cattle to detect proviral B...
متن کاملAnalysis of Syk expression in bovine lymphoma and persistent lymphocytosis induced by bovine leukemia virus.
Spleen tyrosine kinase (Syk) is closely related to various cell reactions. In B-cells, Syk is involved in early B-cell receptor signaling, which affects cellular survival, proliferation and differentiation. Although the kinetics of Syk mRNA and its activity are variable in different types of tumor cells, Syk may have a relation to tumor progression in many human tumors, including B-cell lymphom...
