    11 patients with Hodgkin's disease in remission, including 7 patients with an initial stage III-IV, off treatment for at least 6 months, were tested for blood T lymphocyte functions. All were completely re-evaluated at the end of treatment to assess complete remission. The number of peripheral blood lymphocytes was below 1,200/cu mm 5/11 patients. Absolute numbers of E-rosette-forming T lymphocytes were decreased in 8 patients, whereas active rosettes were normal in 4/6. A slightly increased percentage of EAC rosettes, a marker for B lymphocytes, was found in only 2 patients. In vitro lymphocyte reactivity to a sub-optimal dose of PHA was studied in 9 patients. A statistically significant defect of lymphocyte transformation was observed in the patient group T lymphocytes. A membrane change is suggested rather than a true depletion. The persistance of such abnormalities long after treatment may raise the question of a complementary immunostimulating treatment in these patients.

    Lymphoid Cells and Tissues

    Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
    Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

    Cells of the Adaptive Immune Response

    The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

    Immunodeficiency Diseases

    Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
    There are three main causes of immunodeficiency disorders...

    Cytomegalovirus Disease

    Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
