Lymphoblast: germ cells of the immune system
Lymphoblasts are cells that play an important role in the body's immune system. The term "lymphoblast" comes from the Greek word "blastos", which means "germ" or "embryo", and the prefix "lympho-", which indicates the connection with lymphoid tissue.
Lymphoblasts are the precursors of lymphocytes - cells responsible for the immune response and protecting the body from infections and other pathogenic influences. They are formed in the bone marrow from hematopoietic stem cells and undergo a process of differentiation to become different types of lymphocytes, such as B lymphocytes, T lymphocytes and natural killer cells.
It is important to note that lymphoblasts have a high ability to divide and grow. They undergo active reproduction to ensure continuous renewal of the lymphocyte population in the body. This process is necessary to maintain normal functioning of the immune system.
Lymphoblasts are of particular interest in cancer. Uncontrolled proliferation and accumulation of lymphoblasts can lead to the development of various forms of lymphoblastic leukemia, such as acute lymphoblastic leukemia (ALL) or acute lymphoblastic lymphoma (ALL). These diseases require immediate treatment and monitoring.
Various research methods are used to identify lymphoblasts and evaluate their condition, including blood tests, cytological studies, immunohistochemical studies and molecular genetic tests. These methods make it possible to determine the type of lymphoblasts, their maturity and the degree of malignant transformation.
In conclusion, lymphoblasts are important cells in the body's immune system. Their ability to actively divide and differentiate allows them to maintain the normal functioning of the immune system. However, with uncontrolled reproduction, lymphoblasts can become the object of cancer, requiring specialized treatment and monitoring.
Lymphogenic and neurogenic theories of immune development. > Every person is born immune, but his specific immunity has not yet formed. Plasma proteins are those cells that play a key role in the immune system - lymphocytes (lymphocytic).
Lymphocytes differentiate in the bone marrow and normally rare mature cells circulate in the blood.
One of the theories of how this happens is considered to be lyophobic (neutron). During their development, lymphocytes “recruit” genes and mature in the bone marrow space, in special sections, after which they return to the blood. If the genes correspond to a given age, it is easier for a person to fight infection. The older the lymphocyte, the weaker its activity. There are a number of reasons why maturation may be interrupted:
* Residence in tissue cells. For example, lymphocytes that are able to penetrate the skin barrier during immunization. * External causes, such as radiation or other factors that disrupt the lymphocyte maturation cycle. Such prerequisites are called lymphocyte induction (their activation). If they are contained directly in the human body, an immune response to specific antigens is formed. Sometimes
