Skin Diseases and Disorders

3.9K
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...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

4.2K
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.

Defense Against Bacterial Pathogens

1.4K
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Skin Cancer01:30

Skin Cancer

4.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Sexually Transmitted Infections

322
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Infection01:20

Infection

8.0K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Resumen
Este resumen es generado por máquina.

Staphylococcus aureus libera una proteasa V8 que desencadena el picor mediante la activación del receptor activado por la proteasa neuronal 1. Esta modulación neurosensorial microbiana conduce al rascado y empeora la infección e inflamación de la piel.

Área de la Ciencia:

  • Microbiología
  • La neurociencia
  • Inmunología

Sus antecedentes:

  • La picazón es un síntoma común que puede empeorar las condiciones de la piel.
  • Las infecciones y la inflamación a menudo están asociadas con la patología de la piel.

Objetivo del estudio:

  • Para identificar los factores microbianos responsables del picor en las infecciones por Staphylococcus aureus.
  • Para entender el mecanismo por el cual los microbios desencadenan picazón y daño posterior de la piel.

Principales métodos:

  • El estudio identificó una proteasa específica de Staphylococcus aureus.
  • Investigaron la interacción de esta proteasa con los receptores neuronales.
  • Se evaluaron las consecuencias de esta interacción en la patología e infección de la piel.

Principales resultados:

  • Staphylococcus aureus libera la proteasa V8, un factor clave en el desencadenamiento de la picazón.
  • Esta proteasa activa el receptor 1 activado por la proteasa en las neuronas.
  • El rascado inducido por esta picazón exacerba el daño de la piel y potencia la infección.

Conclusiones:

  • La modulación neurosensorial microbiana juega un papel importante en la patología de la piel.
  • La proteasa V8 de Staphylococcus aureus es una causa directa de picazón.
  • Dirigirse a esta vía podría ofrecer nuevas estrategias para controlar las infecciones de la piel.
