Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

1.5K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

Cells of the Innate Immune Response

1.7K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Antigen Presenting Cells

1.8K
The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

Cells of the Adaptive Immune Response01:23

Cells of the Adaptive Immune Response

1.0K
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...

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

536
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and...

Área de la Ciencia:

  • Inmunología
  • Hepatología
  • Patología

Sus antecedentes:

  • La lesión hepática puede comprometer su defensa contra los patógenos.
  • Los patógenos transmitidos por la sangre representan una amenaza significativa para la salud del hígado.

Objetivo del estudio:

  • Investigar el papel de los agregados de macrófagos en la captura de patógenos transmitidos por la sangre dentro del tejido hepático lesionado.

Principales métodos:

  • Utilizó técnicas avanzadas de imagen para visualizar agregados de macrófagos in situ.
  • Empleó patógenos etiquetados con fluorescencia para rastrear su interacción con los macrófagos.

Principales resultados:

  • Se han observado agregados de macrófagos que envuelven y atrapan activamente patógenos transmitidos por la sangre.
  • Demostró una reducción significativa en la diseminación de patógenos en presencia de estos agregados.

Conclusiones:

  • Los agregados de macrófagos son actores clave en la respuesta inmune innata a la lesión hepática.
  • Estos agregados forman una barrera crítica contra la propagación sistémica de infecciones transmitidas por la sangre en el hígado.
