Mechanisms of Contact Photosensitivity in Mice: II: Langerhans Cells Are Required for Successful Induction of Contact Photosensitivity to TSCA

Photosensitivity due to ampiroxicam.

Photosensitivity from colophony in a case of chronic actinic dermatitis associated with contact allergy from colophony.

Sir, applying colophony 0.02% in white petrolatum or the vehicle alone. They were similar to each other at 24 h after irradiation, Chronic actinic dermatitis (1) is an idiopathic photosensitivity disorder.A high incidence of a previous chronic contact allergy while `̀ MEDs’’ at 48 h after irradiation upon applying colophony were de® nitely lower than those upon applying white caused by several m...

Photosensitivity due to thiazides.

Thiazides are widely used diuretics that first became available in the 1950s. The first reports of photosensitivity reactions to thiazides were published shortly after the introduction of these drugs, but few cases have been described since. We review all the cases of photosensitivity due to thiazides published up to December 2011. We found 62 cases, 33 in women and 29 in men. The most common p...

Physiology of human photosensitivity.

Human epileptic photosensitivity has been studied in several ways. (a) Visual stimulation that resembles the stimulation normally responsible for seizures, such as that from televisions or videogames, both of which typically use cathode ray tubes in which the display is created in a flickering pattern. Such stimulation is often rendered yet more epileptogenic by programmes with content that als...

Functional caspase-1 is required for Langerhans cell migration and optimal contact sensitization in mice.

Langerhans cell (LC) migration from epidermis to draining lymph node is a critical first step in cutaneous immune responses. Both TNF-alpha and IL-1 beta are important signals governing this process, but the potential regulatory role of IL-1 alpha processing by caspase-1 is unknown. In wild-type (WT) mice, application of the contact allergens 2,4-dinitrofluorobenzine and oxazolone lead to a mar...
