El virus de la leucemia de células T humanas no es lisado por el suero humano
Nature
|July 1, 1984
Resumen
El suero humano normal inactiva muchos retrovirus, pero no el virus de la leucemia de células T humanas (HTLV). Esta resistencia al complemento puede explicar el HTLV.
Área de la Ciencia:
- Virología Virología.
- Inmunología Inmunología.
- Retrovirología humana retrovirología humana.
Sus antecedentes:
- Los retrovirus animales suelen ser inactivados por el suero humano normal, lo que indica la activación del complemento.
- El virus de la leucemia de células T humanas (HTLV) es un retrovirus asociado con la leucemia/linfoma de células T adultas (ATL).
- El HTLV se transmite con frecuencia horizontalmente entre los seres humanos, con muchos portadores identificados a nivel mundial.
Objetivo del estudio:
- Investigar la interacción entre el HTLV y el sistema de complemento humano.
- Para determinar si el HTLV es susceptible a la lisis mediada por el complemento por el suero humano normal.
Principales métodos:
- Exposición del HTLV al suero humano normal.
- Observación de la lisis o inactivación del virus.
- Comparación con la susceptibilidad conocida de otros retrovirus animales al suero humano.
Principales resultados:
- A diferencia de otros retrovirus animales, el HTLV no fue inactivado ni lisado por el suero humano normal.
- Esto sugiere que el HTLV evita la activación directa del complemento y la lisis.
Conclusiones:
- El HTLV exhibe resistencia al sistema de complemento humano.
- Esta resistencia puede ser un factor clave en la infectividad y persistencia del HTLV dentro de las poblaciones humanas.
- La comprensión de este mecanismo podría informar las estrategias contra la transmisión HTLV.

Overview
Structure and Function of Leukocytes
An adult in good health typically has between 4,500 and 11,000 leukocytes, or white blood cells, per microliter of blood, which constitutes about 1% of the total blood volume. Unlike red blood cells, white blood cells contain a nucleus and other cellular organelles but do not have hemoglobin. Most white blood cells reside in connective tissues, particularly in lymphatic organs such as the lymph nodes, with only a small fraction present in circulating blood.

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.

Hypersensitivity Reactions: Cytolytic Reactions
Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...
Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
