Abstract The CD40R-CD40 ligand pathway is a key co-stimulatory for driving T cell-dependent B cell activation and humoral immune responses. This has been implicated in the pathogenesis of several autoimmune diseases including thyroiditis, type 1 diabetes, Crohn’s disease, inflammatory bowel psoriasis, multiple sclerosis, rheumatoid arthritis, systemic lupus erythematosus Sjogren’s syndrome. Alt...

Full-length cDNAs encoding macrophage inhibitory factor-2 (MIF-2) were cloned from Teladorsagia circumcincta (TcMIF-2) and Haemonchus contortus (HcMIF-2). TcMIF-2 HcMIF-2 cDNA (342 bp) encoded proteins of 114 amino acids, each which was present as a single band about 16 kDa on SDS-PAGE. Multiple alignments the protein sequences showed homology 84% between HcMIF-2, 54–76% with MIF-2s seven nemat...

The activity of excitatory neurons is controlled by a highly diverse population of inhibitory interneurons. These cells show a high level of physiological, morphological and neurochemical heterogeneity, and play highly specific roles in neuronal circuits. In the mammalian hippocampus, these are divided into 21 different subtypes of GABAergic interneurons based on their expression of different m...

Background: Patients with stiff-person syndrome (SPS) have circulating antibodies against glutamic acid decarboxylase, the rate-limiting enzyme responsible for the synthesis of -aminobutyric acid (GABA). Although the patients’ symptoms of stiffness and unexpected spasms can be explained on the basis of reduced or impaired inhibitory neurotransmitters, such as GABA, it is unclear whether the lev...

introduction:torch infections causing via toxoplasma gondii, other microorganisms (e.g., treponema pallidum), rubella virus, cytomegalovirus (cmv) and the herpes simplex virus (hsv) types 1 and 2 during the first trimester of pregnancy can lead to severe fetal anomalies or even fetal loss. the current study determined the serological data of torch infections in women who were in their first tri...

a survey was carried out in five provinces of iran (kerman, sistan and baluchestan, hormozgan, khorasan and yazd) for the presence of alfalfa mosaic virus (amv) sero-types in alfalfa during 2002 to 2003. the number of samples collected was 250, represent-ing the diversity and geographical distribution of amv in these areas. diagnosis was car-ried out using polyclonal (pabs) and monoclonal (mabs...

Antibodies are known to affect the morphology, growth, and metabolism of mollicutes and thus may serve as candidate molecules for a plantibody-based control strategy for plant-pathogenic spiroplasmas and phytoplasmas. Recombinant single-chain variable fragment (scFv) antibodies are easy to engineer and express in plants, but their inhibitory effects on mollicutes have never been evaluated and c...

The concentration of specific alloantibody in purified mouse immunoglobulin preparations was determined. When passively transferred in adequate doses, IgM, IgG1, and IgG2 antibodies all induced tumor enhancement in allogeneic hosts. IgM and IgG2 antibodies in high concentration led to inhibition of tumor growth. IgM and either IgG1 or IgG2 had additive effects on tumor enhancement. IgG1, but no...

OBJECTIVE Autoimmune-mediated anti-α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) encephalitis is a severe but treatment-responsive disorder with prominent short-term memory loss and seizures. The mechanisms by which patient antibodies affect synapses and neurons leading to symptoms are poorly understood. METHODS The effects of patient antibodies on cultures of live rat...

Background: Antiphospholipid antibodies (aPL) are a heterogeneous family of anti-bodies associated with thrombosis and other complications. Objective: To study the prevalence of aPL in patients with thrombosis at Aleppo University Hospitals, Syria. Methods: One hundred and fifty-seven patients with venous and arterial thrombosis and 63 healthy controls were studied. Anticardiolipin antibodies (...
