May 2018 in “British journal of dermatology/British journal of dermatology, Supplement” Alopecia areata is likely an autoimmune disease with unclear triggers, involving various immune cells and molecules, and currently has no cure.
129 citations,
May 2015 in “Cell Stem Cell” Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
60 citations,
September 2015 in “Expert Review of Clinical Immunology” Lymphocytes, especially CD8+ T cells, play a key role in causing alopecia areata, and targeting them may lead to new treatments.
32 citations,
May 2012 in “PloS one” Thymic transplantation normalized some T-cells but not others, maintaining immune function.
31 citations,
February 2014 in “Inflammation Research” Lower CD200R1 on certain immune cells is linked to more severe rheumatoid arthritis and immune imbalance.
6 citations,
