Skin Diseases and Disorders01:23

Skin Diseases and Disorders

5.8K
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...

Surface Membrane Barriers01:18

Surface Membrane Barriers

3.0K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Defense Mechanism Against Infection

9.9K
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...

Allergic Drug Reactions01:27

Allergic Drug Reactions

1.5K
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Drug Toxicity: Allergic Reactions

26
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Defense Against Bacterial Pathogens01:31

Defense Against Bacterial Pathogens

3.0K
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...

Summary
This summary is machine-generated.

Atopic dermatitis involves complex immune, microbial, and skin barrier interactions. Understanding these factors is crucial for developing effective treatments for this heterogeneous skin condition.

Area of Science:

  • Dermatology
  • Immunology
  • Microbiology

Background:

  • Atopic dermatitis is a complex skin condition.
  • Understanding its pathogenesis is key to treatment.

Purpose of the Study:

  • To review studies on immunologic, microbial, and epithelial interactions in atopic dermatitis.
  • To provide an overview of current knowledge on disease pathogenesis.

Main Methods:

  • PubMed literature review (2000-2017).
  • Analysis of meeting abstracts from international dermatology conferences.
  • Inclusion of articles primarily discussing human disease.

Main Results:

  • Atopic dermatitis is a type 2 immune-centered disease with systemic inflammation.
  • Treatment responses are heterogeneous, suggesting other contributing factors.
  • Microbial dysbiosis and epidermal barrier dysfunction are implicated in disease phenotype.

Conclusions:

  • Clinical research has advanced understanding of atopic dermatitis pathogenesis.
  • Future clinical trials will further elucidate this complex and heterogeneous skin disease.
