Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.2K
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.
There are three main causes of immunodeficiency...

Factors Affecting the Risk of Infection

12.2K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Autoimmune Disorders01:29

Autoimmune Disorders

666
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Skin Diseases and Disorders

4.1K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

321
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Área de la Ciencia:

  • Inmunología
  • Biología mitocondrial
  • La genética

Sus antecedentes:

  • Las enfermedades de inmunodeficiencia primaria (EIP) son trastornos hereditarios que causan disfunción inmune, infecciones, autoinmunidad y cáncer.
  • Las investigaciones emergentes revelan el papel crucial de la inflamación en la patogénesis de la EIP, más allá de los defectos celulares inmunes tradicionales.

Objetivo del estudio:

  • Revisar la compleja interacción entre la disfunción mitocondrial y la inflamación en las EIP.
  • Explorar cómo los defectos genéticos en las EIP interrumpen la homeostasis inmune y promueven la inflamación.
  • Para resaltar las posibles estrategias terapéuticas dirigidas a las vías mitocondriales.

Principales métodos:

  • Revisión de la literatura sobre los defectos genéticos en las EIP.
  • Análisis de los mecanismos que vinculan la disfunción mitocondrial con la inflamación (disregulación de las citocinas, estrés oxidativo, activación del inflamatorio).
  • Exploración de las vías mitocondriales (señalización de calcio, ATP sintasa, mPTP) en la patogénesis de la EIP.

Principales resultados:

  • Los defectos genéticos en las EIP interrumpen la homeostasis inmune, lo que lleva a estados proinflamatorios.
  • La disfunción mitocondrial, el estrés oxidativo y la inflamación forman un ciclo autosuficiente.
  • El deterioro de la función mitocondrial puede ser un mecanismo central que conecta la inmunodeficiencia y la hiperinflamación.

Conclusiones:

  • La disfunción mitocondrial es un factor clave en la patogénesis de la EIP, que vincula la inmunodeficiencia con la inflamación.
  • Comprender estas interacciones ofrece nuevos conocimientos sobre los mecanismos de la EIP.
  • Dirigirse a las vías mitocondriales presenta nuevas oportunidades terapéuticas para las EIP.
