Disorders of Leukocytes01:27

Disorders of Leukocytes

1.3K
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
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...

Lymphoid Cells and Tissues01:18

Lymphoid Cells and Tissues

2.0K
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...

Primary Lymphoid Organs

12.1K
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Bone Marrow Sampling and Transplants

588
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.5K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Area of Science:

  • Hematology
  • Oncology
  • Genetics

Background:

  • Lymphoblastic leukemias and lymphomas are common childhood cancers, representing most acute leukemias.
  • These neoplasms also occur frequently in adults, originating from either B-cell or T-cell lineages.
  • Immature precursor cells characterize these neoplastic processes.

Purpose of the Study:

  • To highlight the differences in classification between B-cell and T-cell lymphoblastic neoplasms.
  • To emphasize the prognostic and therapeutic significance of cytogenetic abnormalities.

Main Methods:

  • Review of current classification systems for lymphoblastic neoplasms.
  • Analysis of the role of genetic and molecular findings in B-cell neoplasm classification.
  • Examination of cytogenetic abnormalities in T-cell lymphoid origin neoplasms.

Main Results:

  • B-cell lymphoblastic neoplasm classification relies heavily on genetic and molecular data.
  • T-cell lymphoid origin neoplasms have a different classification approach.
  • Recurrent cytogenetic abnormalities are common and influence prognosis and treatment.

Conclusions:

  • Accurate classification of lymphoblastic leukemia/lymphoma is essential for effective treatment.
  • Genetic and molecular profiling are critical for B-cell neoplasms.
  • Further research into T-cell neoplasm classification may improve patient outcomes.
