High- and low-leukemogenic variants of the radiation leukemia virus (RadLV) differ in ability to induce
Abstract:
Adult C57BL/6 mice inoculated intrathymically (i.t.) with the highly leukemogenic variant of the radiation leukemia virus (A-RadLV) develop suppressor cells capable of specifically abrogating a potential anti-tumor cytotoxic response in vitro. Suppressor cells were generated directly by the virus, independently of an initiation of a leukemogenic process. Inoculation of C57BL/6 animals with the low leukemogenic D-RadLV variant did not result in suppressor cell generation. It is proposed that induction of tumor-specific immune suppression by A-RadLV is essential for tumor progression, and the leukemogenic activity of D-RadLV is attributed to its inability to recruit suppressor cells.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

01:27Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
