White adipose tissue (WAT) is innervated by postganglionic sympathetic nervous system (SNS) neurons, suggesting that lipid mobilization could be regulated by the SNS [T. G. Youngstrom and T. J. Bartness. Am. J. Physiol. 268 (Regulatory Integrative Comp. Physiol. 37): R744-R751, 1995]. A viral transsynaptic retrograde tract tracer, the pseudorabies virus(More)
Linear immunoglobulin A dermatosis is a rare autoimmune bullous disease, but the most common autoimmune bullous dermatosis in children. We report a typical exuberant case of linear IgA dermatosis in a ten-month old child, who showed good response to treatment with corticosteroids and dapsone.
It is well established that autoantibodies against desmoglein 3 and desmoglein 1 (Dsg1) are relevant in the pathogenesis of pemphigus vulgaris and pemphigus foliaceus, including its endemic form fogo selvagem (FS). Isolated reports have shown that in certain patients with these diseases, autoantibodies against other desmosomal cadherins and E-cadherin may(More)
INTRODUCTION Pemphigoid gestationis, also known as herpes gestationis, is a rare autoimmune blistering disease associated with pregnancy. It usually occurs during the second or third trimester, but it may be present at any stage of pregnancy or the puerperium. The clinical, histologic, and immunopathological features of pemphigoid gestationis are similar to(More)
Atopic dermatitis is a chronic inflammatory skin disease with a complex pathogenesis, where changes in skin barrier and imbalance of the immune system are relevant factors. The skin forms a mechanic and immune barrier, regulating water loss from the internal to the external environment, and protecting the individual from external aggressions, such as(More)
We report here a relationship between intramolecular epitope spreading and the clinical onset of the endemic form of pemphigus foliaceus in a Brazilian community with a high prevalence and incidence of the disease. Also known as Fogo Selvagem (FS), this disease is characterized by severe skin blistering and pathogenic anti-desmoglein-1 (Dsg1)(More)
OBJECTIVE Atopic dermatitis (AD) is a chronic inflammatory disease causing intense pruritus, and with typical clinical features. There are few epidemiological studies concerning AD in adults, as well as little information about its prognostic. The aim of this study was to evaluate the clinical and epidemiological course of adults with AD. METHODS 80(More)
The environmental factors that contribute to the development of autoimmune diseases are largely unknown. Endemic pemphigus foliaceus in humans, known as Fogo Selvagem (FS) in Brazil, is mediated by pathogenic IgG4 autoantibodies against desmoglein 1 (Dsg1). Clusters of FS overlap with those of leishmaniasis, a disease transmitted by sand fly (Lutzomyia(More)
Lichen planus (LP) is a chronic mucocutaneous inflammatory disease. Evaluating the balance between regulatory T cells and effector T cells could be useful for monitoring the proinflammatory profile of LP. Therefore, this study aimed to assess populations of dendritic cells (DCs) and regulatory and effector T cells in peripheral blood samples collected from(More)
Fogo Selvagem (FS) is an endemic form of pemphigus foliaceus (PF) which is prevalent in certain regions of Brazil (Diaz et al., 1989). Genetic and environmental factors such as insect bites may contribute to the development of FS (Aoki et al., 2004; Diaz et al., 1989; Moraes et al., 1997). Blister formation in FS is mediated by predominantly IgG4(More)
