Intravital Imaging of Dynamic Behaviors of Leukocytes in UVB-induced Skin Inflammation
Ultraviolet B (UVB) irradiation diminishes surface densities of Langerhans cells (LCs) in the epidermis of the skin. Other leukocytes, such as neutrophils and macrophages, are recruited to the irradiated sites due to chemo-attracting factors released from the altered microenvironment. However, …

Expression und Funktion der Acyl-CoA-Synthetase 5 in der humanen Epidermis
… that cellular lipid metabolism can be altered by UVB irradiation in correlation with stress response. UVB irradiation of HaCaT in vitro resulted in slight modification of ACSL5 expression. This could be observed both on RNA and protein level. These observation indicates that ACSL5 might be …

Transcriptional functions of the corepressor Sin3A in skin
… this I performed pilot experiments using UVB irradiation of skin that has one copy of Sin3A deleted in the basal layer of the epidermis. Under normal conditions, these mice have no identifiable phenotype, but pilot experiments demonstrated that after short term and long term UVB …

Characterising the biological response to ultraviolet radiation
… thought to play a larger role in photoaging than UVB. Despite this current sum protection methods assess UVA protection only as a ratio of UVA: UVB that is blocked by the sun cream. Therefore it is desirable to have a more biologically relevant method to assess UVA protection offered by a sun …

AMPHOTERIC POLYAMIDOAMINES AS FUNCTIONAL SPECIALTY POLYMERS
… in accelerated photoaging tests under UVA-UVB irradiation. To gain deeper insight into this phenomenon, the photodegradation mechanism both in solution and in the solid state was investigated during the research period at the Université Clermont Auvergne. Photodegradation was evaluated …

Einfluss von UVB-Strahlung auf die Antigen-präsentierende Funktion Dendritischer Zellen - Apoptoseinduktion bei T-Zellen
… der Immunantwort durch niedrigdosierte UVB-Bestrahlung muriner LZ konnte bereits gezeigt werden (Denfeld et al., 1998; Simon et al., 1992; Simon et al., 1991). <br>Wir fanden eine verminderte Proliferation muriner TZ, die mit allogenen UVB-DZ koinkubiert waren. Diese …

Heat stress: A risk factor for skin carcinogenesis
… for skin carcinogenesis. UV, particularly the UVB spectrum, causes formation of cyclobutane pyrimidine dimers (CPD) in cellular DNA. Persistent and incorrectly repaired CPDs lead to DNA mutations and consequently, formation of cutaneous lesions. Interestingly, recent epidemiological studies …
