Abstract: | Alterations in blood lymphocyte subsets may be involved in the development of overt myeloma. Naive (CD4+CD45RA+) and memory (CD4+CD45RO+) helper T-cell subsets are important effectors of immune T-cell regulation. We analyzed the distribution of these blood lymphocyte subpopulations in patients with monoclonal gammopathies, considering the type of disorder, clinical stage, and treatment status. |
