INTRODUCTION During HIV-1 infection the B-cell compartment undergoes profound changes towards terminal differentiation, which are only partially restored by antiretroviral therapy (cART). MATERIALS AND METHODS To investigate the impact of infection as early as during primary HIV-1 infection (PHI) we assessed distribution of B-cell subsets in 19 PHI and 25 chronic HIV-1-infected (CHI) individu...
Analysis of immunoglobulin gene rearrangements in 16 B-cell lineages clonally propagated from two mononucleosis patients supported the notion that mononucleosis is a polyclonal B-lymphoproliferative disorder. Three of seven cell clones from a patient with a fatal B lymphoma revealed the same pattern of immunoglobulin gene rearrangement, indicating that this patient's disease was oligoclonal. Th...
از جمله راه های تعیین تنوع و روابط فیلوژنتیکی در حشرات، استفاده از خصوصیات ظاهری و نشانگرهای مولکولی می باشد. در این تحقیق تنوع و روابط فیلوژنتیکی برخی از بالتوری ها از نظر ریخت شناسی و توالی بخشی از ژن کد کننده سیتوکروم اکسیداز i بررسی گردید. جمع آوری نمونه ها در استان کردستان در شهرستان های کامیاران، بانه، سنندج، دیواندره، مریوان و سقز انجام شد. برای جمع آوری بالتوری ها از تله نوری و تور دستی...
BACKGROUND X-linked agammaglobulinemia (XLA) is a rare inherited disease characterized by recurrent bacterial infections, a paucity or absence of peripheral lymphoid tissue, an absence of circulating B cells, and marked depression of serum IgG, IgA, and IgM. Germline mutation of the BTK gene has been identified as a cause of XLA. These mutations cause defects in early B cell development. CASE...
This study describes long-term-cultured lines and clones of cytotoxic T cells (Tc) with specificity for determinants of the Igh-1(b) immunoglobulin allotype. These Tc clones were initiated by repeated stimulation of immune spleen cells from BALB/c mice with an Igh-1(b)-producing myeloma, and then they were maintained in medium supplemented with mitogen-induced growth factors in the absence offu...
