Las colonias de linfocitos T en enfermedades malignas
Lancet (London, England)
|November 20, 1976
Resumen
Este estudio muestra que el cultivo de colonias de linfocitos T puede detectar enfermedades malignas. Se encontraron resultados anormales en el 89% de los pacientes con cáncer, lo que indica su potencial diagnóstico para la investigación y el monitoreo del cáncer.
Área de la Ciencia:
- Inmunología Inmunología.
- Oncología Oncología.
- Biología celular Biología celular.
Sus antecedentes:
- La formación de colonias de linfocitos T es un indicador clave de la función inmune.
- La evaluación de las respuestas de los linfocitos T es crucial para comprender y manejar las neoplasias malignas.
Objetivo del estudio:
- Evaluar la utilidad diagnóstica del cultivo de colonias de linfocitos T en pacientes con enfermedades malignas.
- Para determinar la correlación entre la formación anormal de colonias de linfocitos T y la presencia de cáncer.
Principales métodos:
- Cultivo de colonias de linfocitos T de 106 sujetos, incluidos controles sanos, pacientes hospitalizados y pacientes con cáncer.
- Analizar la formación de colonias para detectar anomalías en diferentes grupos de pacientes.
Principales resultados:
- Se observaron resultados anormales en las colonias de linfocitos T en el 89% de los pacientes con enfermedad maligna.
- Se observó una alta tasa de anormalidad (96%) en pacientes con carcinomas (23 de 24).
Conclusiones:
- El cultivo de colonias de linfocitos T demuestra un potencial significativo como biomarcador para la detección de enfermedades malignas.
- La prueba puede ser valiosa para la investigación del cáncer, el diagnóstico y el monitoreo de la progresión de la enfermedad.

Metastasis
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Disorders of Leukocytes
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 system...

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...

Primary Lymphoid Organs
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...

Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

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...
