Phototherapies like photodynamic therapy (PDT), UVA1, UVB, and PUVA treat skin
diseases. These phototherapies work because they alter cytokine profiles, change immune …

Background Apoptosis, or programmed cell death, is an essential physiological process that
controls cell numbers during physiological processes, and eliminates abnormal cells that …

Sunburn cells, single standing cells with typical morphologic features occurring in UV‐
exposed skin, have been recognized as keratinocytes undergoing apoptosis following UV …

Publisher Summary Ultraviolet (UV) radiation has been used for decades in the treatment of
patients with a variety of T-cell-mediated skin diseases, including atopic dermatitis and …

Ultraviolet radiation (UV) induces a variety of biological effects which include the induction of
programmed cell death. UV-induced apoptosis seems to represent a controlled scavenging …

Phototherapy has been largely empirical. Thus, despite the long term use its mechanisms of
action are quite unclear. Because of the recent achievements in photoimmunology and …

In multicellular organisms, controlled destruction of selected cell populations is an important
component of development, differentiation and adaption. Unwanted cells are eliminated …

The ultraviolet (UV) B portion of the UV light has been recognized as the most prominent risk
factor for the development of skin cancer, the most common malignancy in the Caucasian …

The induction of apoptosis in keratinocytes by ultraviolet (UV)-irradiation is considered to be
a protective function against skin cancer. UV-induced DNA damage is a crucial event in UVB …

Epidemiological and experimental evidence has supported the notion that solar ultraviolet
(UV) radiation is the leading cause of skin cell damage and skin cancer. Non‐melanoma …
