Immunology and Genetics

The document summarizes research findings in the field of dermatology, immunology, and genetics from 14 years ago. It includes a retrospective study on nine patients identifying Borrelia afzelii as a cause of borrelial lymphocytoma in France, and a gene-wide association study suggesting a link between the CYP19A1 gene and female pattern hair loss in Caucasian women. It also reports on a novel mutation in the PRKARIA gene in a patient with Carney complex, the role of major histocompatibility complex alleles in keloid scarring, and a new clinical phenotype of acral self-healing collodion baby due to a TGM1 mutation. Additionally, it discusses the development of a murine model for systemic sclerosis, the correlation of bcl-xL expression with prognosis in primary cutaneous follicle center lymphomas, and the influence of genetic variations on the risk of erythema nodosum in sarcoidosis patients. The document also covers research on various genetic mutations and their effects on skin diseases, the immunomodulatory activities of a Vitamin D3 analogue, and the functions of natural killer T cells. However, specific participant numbers are only provided for the study involving 110 healthy individuals tested for the PRKARIA mutation.
