Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

13.1K
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...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.8K
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...

Development of Immunocompetence01:22

Development of Immunocompetence

669
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Immune Response Against Viral Pathogens01:29

Immune Response Against Viral Pathogens

1.6K
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

745
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...

Area of Science:

  • Immunology
  • Gerontology
  • Nutrition Science

Background:

  • Aging leads to detrimental immune system changes, increasing infection risks in the elderly.
  • Poor nutritional status exacerbates age-related immune dysfunction.
  • Micronutrient deficiencies are a global health issue linked to infections.

Purpose of the Study:

  • To review the impact of micronutrient supplementation on immune function in aging individuals.
  • To explore how restoring micronutrient levels can enhance immune resistance to infections.

Main Methods:

  • Literature review focusing on studies examining micronutrient supplementation and immune function in aging populations.
  • Analysis of research on the relationship between nutritional status, immune response, and infection in the elderly.

Main Results:

  • Micronutrient deficiencies negatively affect immune function in older adults.
  • Supplementation with deficient micronutrients can improve immune parameters.
  • Enhanced immune function may lead to increased resistance and faster recovery from infections.

Conclusions:

  • Addressing micronutrient deficiencies is crucial for supporting immune health in aging.
  • Micronutrient supplementation holds potential for mitigating infection-related morbidity and mortality in the elderly.
  • Further research is warranted to optimize supplementation strategies for geriatric immune support.
