New insights in vitiligo: cellular immune response

Background Vitiligo is a skin disorder that affects 1% to 2% of the world population, independently of ethnicity. It presents with white plaques and skin discoloration. The presence of antibodies against melanocytes confirms the autoimmune phenomena in this disease. Regarding cellular imune response in active vitiligo, it seems to be an imbalance between T cell CD8+ and CD4+, and, moreover, an ...

New insights and new therapies in vitiligo.

VITILIGO IS A RELATIVELY COMmon, acquired pigmentary disorder characterized by areas of depigmented skin resulting from loss of epidermal melanocytes. The prevalence of this disease varies from 0.1% to 2% in various global populations. Onset may occur at any age, but the incidence usually peaks in the second and third decades of life. Patterns of distribution of the disease include the generali...

Evaluation of Cellular Immune Response against Purified Antigen 85 in Patients with Tuberculosis

Background: Tuberculosis (TB) remains an important health problem throughout the world. Despite its significance in public health, mechanisms of protective immunity against Mycobacyerium Tuberculosis in humans have not yet been understood. Objective: To evaluate cell mediated immune response against purified Ag 85, PPD and Phytohemagglutinin (PHA) in patients with tuberculosis and healthy tuber...

New Insights in Cutaneous Melanoma Immune-Therapy — Tackling Immune-Suppression and Specific Anti- Tumoral Response

Cellular Events in the Immune Response

Cell suspensions from the spleens of normal mice or mice injected with sheep erythrocytes were separated on a discontinous bovine serum albumin density gradient. Four bands or subpopulations were obtained and were assayed for antibody-forming cells, and for antigen-sensitive precursor cells. The antibody-forming cells were assayed by the hemolytic plaque assay and the antigen-sensitive precurso...
