Skin Diseases and Disorders

6.1K
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...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

14.5K
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...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

10.6K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Fungal Phylum Microsporidia01:28

Fungal Phylum Microsporidia

681
Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

The Skin Microbiota01:27

The Skin Microbiota

16
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

Area of Science:

  • Immunology
  • Mycology
  • Dermatology

Background:

  • Candida albicans is a fungus that normally lives on the skin but can cause opportunistic infections.
  • Infections range from superficial to disseminated candidiasis, including chronic mucocutaneous candidiasis (CMC).
  • Immune responses vary by infection site, indicating tissue-specific immunity.

Purpose of the Study:

  • To review cellular pathways involved in skin immunity against Candida albicans.
  • To highlight insights from human and mouse skin infection models.
  • To understand host-pathogen interactions in cutaneous candidiasis.

Main Methods:

  • Review of established and emerging research on cutaneous antifungal immunity.
  • Analysis of genetic studies in chronic mucocutaneous candidiasis (CMC) patients.
  • Comparative examination of human and mouse skin models.

Main Results:

  • Host genetics reveal conserved pathways for immune recognition of C. albicans.
  • Tissue compartmentalization influences immune responses to C. albicans.
  • Specific cellular pathways are crucial for promoting skin antifungal immunity.

Conclusions:

  • Cutaneous immunity against Candida albicans involves complex, site-specific cellular pathways.
  • Understanding these pathways is key to combating opportunistic fungal skin infections.
  • Further research in human and mouse models will elucidate antifungal defense mechanisms.
