Although a heterozygous deficiency of either complement component C4A or C4B is common, and each has a frequency of approximately 20% in a Caucasian population, complete deficiencies of both C4A and C4B proteins are extremely rare. In this paper the clinical courses for seven complete C4 deficiency patients are described in detail, and the molecular defects for complete C4 deficiencies are eluc...
A new paradigm in human genetics is high frequencies of inter-individual variations in copy numbers of specific genomic DNA segments. Such common copy number variation (CNV) loci often contain genes engaged in host-environment interaction including those involved in immune effector functions. DNA sequences within a CNV locus often share a high degree of identity but beneficial or deleterious po...
CONTEXT Excess production of aldosterone or cortisol has profound effects on cardiovascular function and impacts other major organ systems. The mechanisms leading to the autonomous hypersecretion of aldosterone or cortisol in aldosterone-producing adenoma (APA) or cortisol-producing adenoma (CPA) are unknown. OBJECTIVE The objective of this study was to compare the expression profiles of seve...
In the human genome, the major histocompatibility complex class III region on chromosome 6p21.3 stands out as an area of remarkably high gene density. 2 Within this region, a section of particular complexity centres around the C4 genes, which encode the fourth component of complement. Centromeric to C4 lies the CYP21A2 gene, which encodes steroid 21-hydroxylase, a key enzyme in the biosynthesis...
بیماری میوه سبز مرکبات توسط باکتری سخت کشت candidatus liberobacter asiaticus ایجاد می شود که اولین بار در چین توصیف شده است و در سال 1919 با نام رسمی huanglongbing معرفی گردید. این بیماری یکی از پرخسارت ترین بیماری های مرکبات درجنوب شرقی آسیا، شبه قاره هند، آفریقای جنوبی و شبه جزیره عربستان است. این بیماری در سال 1386 از جنوب ایران گزارش گردید. برای درک مکانیسم مولکولی برهمکنش میزبان-پاتوژن از ...
