Role of Lymphocyte Subpopulations in The Immunopathogenesis of Psoriasis and The Effect of Narrow Band UVB Phototherapy on The Immunological Profile of Psoriasis Patients.

Psoriasis is one of the most common chronic, inflammatory, T-cell-mediated autoimmune diseases. Narrow-band UVB (NB-UVB) therapy is widely used in the treatment of psoriasis; however, its mechanism of action is still not well understood. The objective of this study was to investigate the circulating T-lymphocyte subpopulations in psoriasis patients before and after NB-UVB, to get insights into the mechanism of NB-UVB in the treatment of psoriasis.

Isolation, Identification, and In Vitro Antifungal Susceptibility Testing of Dermatophytes from Clinical Samples at Sohag University Hospital in Egypt.

Aim: The objective of this study was to isolate, identify, and explore the in-vitro antifungal susceptibility pattern of dermatophytes isolated from clinically suspected cases of dermatophytosis (tinea infections) attending the Dermatology Outpatient Clinic.

Methods: This study was conducted at Sohag University Hospital from December 2014 to December 2015. Clinical samples (e.

The potential role of cell surface complement regulators and circulating CD4+ CD25+ T-cells in the development of autoimmune myasthenia gravis.

Introduction: CD4+CD25+ regulatory T-lymphocytes (T-regs) and regulators of complement activity (RCA) involving CD55 and CD59 play an important role in the prevention of autoimmune diseases. However, their role in the pathogenesis of human autoimmune myasthenia gravis (MG) remains unclear. This study aimed to determine the frequency of peripheral blood T-regs and CD4+ T-helper (T-helper) cells and the red blood cells (RBCs) level of expression of CD55 and CD59 in MG patients.
