Reactivation of pre-existing scars, as a manifestation of cutaneous sarcoidosis, is uncommon and the clinical significance of this odd symptom often remains unrecognised. In the appropriate setting a skin biopsy may serve to establish the diagnosis of sarcoidosis and avoid more invasive attempts at obtaining tissue. The case of a 72 year old man with remote reactivation of multiple cutaneous sc...
Inflammation is a fundamental component of the normal adult wound healing response occurring even in the absence of infection. It performs many beneficial roles such as the clearing of damaged cells and extracellular matrix (ECM), the removal of pathogens that might otherwise multiply and spread, and the secretion of mediators that regulate other aspects of wound healing such as proliferation, ...
Interleukin 17 (IL-17) plays a critical role in inflammation and autoimmunity. Very little is known about IL-17 in protozoa infection. Here, we show that lymphocytes obtained from patients with mucosal leishmaniasis and cutaneous leishmaniasis produce higher levels of IL-17 than do lymphocytes obtained from uninfected control subjects (P<.01). There was a tendency for tissue obtained from patie...
UNLABELLED Skin is a highly ordered immune organ that coordinates rapid responses to external insult while maintaining self-tolerance. In healthy tissue, lymphatic vessels drain fluid and coordinate local immune responses; however, environmental factors induce lymphatic vessel dysfunction, leading to lymph stasis and perturbed regional immunity. These same environmental factors drive the format...
This review focuses on the role of the peripheral nervous system in cutaneous biology and disease. During the last few years, a modern concept of an interactive network between cutaneous nerves, the neuroendocrine axis, and the immune system has been established. We learned that neurocutaneous interactions influence a variety of physiological and pathophysiological functions, including cell gro...
Cutaneous neurogenic inflammation is a complex biological response of the host immune system to noxious stimuli. Present evidence suggests that zinc metalloproteases may play an important role in the regulation of neurogenic inflammation by controlling the local availability of neuropeptides, such as substance P (SP), that are capable of initiating or amplifying cutaneous inflammation after rel...
Skin keratinocytes are major mediators of host immune responses. The skin is also a target for immunologically based inflammation in many pathological states. Activation of protein kinase C (PKC) can induce cutaneous inflammation, but the precise role of each of six cutaneous PKC isoforms (alpha, delta, epsilon, eta, zeta, mu) that regulate normal skin homeostasis or contribute to skin patholog...
