Gamma delta T-cells in human cutaneous immunology
1Dermatology Unit, Royal Postgraduate Medical School, Hammersmith Hospital, London, UK.
Insights
Gamma delta T-cells, a small T-lymphocyte group, are explored in human skin. This review details their presence in healthy and diseased skin, examining their T-cell receptor repertoire in various skin conditions.
Area of Science:
- Immunology
- Dermatology
- Cell Biology
Background:
- Gamma delta T-cells are a minor T-lymphocyte subpopulation in humans.
- The specific role of gamma delta T-cells in normal and diseased human skin remains largely unknown.
- Understanding these cells is crucial for advancing dermatology and immunology.
Purpose of the Study:
- To provide a comprehensive review of T-lymphocytes expressing the gamma delta T-cell receptor (γδ TCR) in human skin.
- To document the occurrence and distribution of gamma delta T-cells in both normal and pathological skin.
- To discuss the experimental findings on the repertoire of gamma delta T-cells in healthy skin and various cutaneous disorders.
Main Methods:
- Comprehensive literature review.
- Analysis of existing experimental findings on gamma delta T-cell occurrence.
- Examination of T-cell receptor repertoire studies in normal and pathological skin.
Main Results:
- Gamma delta T-cells are present in normal human skin.
- These cells are also found in a variety of reactive and malignant skin conditions.
- The repertoire of gamma delta T-cells varies between normal skin and specific skin disorders.
Conclusions:
- Gamma delta T-cells are a component of the immune system in human skin.
- Their presence in diverse skin conditions suggests a potential role in cutaneous immunity and pathology.
- Further research into the gamma delta T-cell repertoire is warranted to elucidate their function in skin health and disease.
Abstract:
Gamma delta T-Cells represent a minor subpopulation of T-lymphocytes in man and their role in normal and diseased human skin is unknown. This article is a comprehensive review of T-lymphocytes bearing the gamma delta T-cell receptor in normal and pathological human skin. Firstly, we have documented the occurrence of gamma delta T-cells in normal skin and in a range of reactive and malignant skin conditions. We have then discussed the experimental findings regarding the repertoire used by gamma delta T-cells in normal human skin and in cutaneous disorders with an increased percentage of gamma delta T-cells.
