Background:  Cytotoxic T lymphocyte–associated antigen 4 (CTLA-4) molecules are expressed on T-cells and inhibit their function by inhibiting activation of subsequent T-cell molecular pathways. Blocking of CTLA-4 inhibits the growth of malignant tumor cells. Anti-CTLA-4 monoclonal antibodies activate the immune system against cancer. Due to several advantages of single-chain antibodi...

Schizophrenia is a chronic psychiatric disorder marked by psychotic symptoms (i.e., hallucinations and delusions), behavioral changes (e.g., apathy, social withdrawal) and cognitive dysfunction (e.g., executive impairment) [1]. Affecting roughly 1% of the general population, schizophrenia exerts a significant socioeconomic burden due to its severity. From an etiopathogenic perspective, schizoph...

Background SARS-CoV-2(Severe acute respiratory syndrome coronavirus 2) has been circulating worldwide for three years. It mainly causes upper tract infection, which can manifest as pulmonary infection and even distress in severe cases. Different autoantibodies be detected patients infected with COVID-19. Objectives To explore related to rheumatic diseases after COVID-19 infection. Methods Ninet...

Selective in vivo delivery of cargo to peripheral nervous system (PNS) has broad clinical and preclinical applications. An important applicability of this approach is systemic delivery of fluorescently conjugated ligands that selectively label PNS, which could allow visualization of peripheral nerves during any surgery. We examine the use of an anti-ganglioside monoclonal antibody (mAb) as sele...

The systemic lupus erythematosus (SLE) is an autoimmune disorder with a broad array of clinical signs. In this research, we aimed to use intravenous immunoglobulins (IVIG) called intacglobin as monotherapy to manage an SLE in three patients. Laboratory investigations for SLE diagnosis were done, including the detection of anti-nuclear antibodies (ANA) and SLE confirmation by detecting high tite...

background: anti-ganglioside antibody assays are widely used for diagnosis of autoimmune peripheral neuropathies. objective: this study aimed to determine serum levels of anti-ganglioside antibodies in children with guillain-barre syndrome by immunoblotting technique and compare the results with those obtained by elisa method. method: in this investigation, 50 children with guillain-barre syndr...

Ganglioside stimulated neurite outgrowth may be due to ganglioside binding to membrane proteins or to intercalation into the membrane. To test that ganglioside binding proteins could be found on neuronal surfaces, anti-idiotypic ganglioside monoclonal antibodies (AIG mAbs) were generated to mimic the biological properties of the GM1 ganglioside. The AIG mAbs were identified by their ability to ...

Background: Anti-ganglioside antibody assays are widely used for diagnosis of autoimmune peripheral neuropathies. Objective: This study aimed to determine serum levels of anti-ganglioside antibodies in children with Guillain-Barre syndrome by immunoblotting technique and compare the results with those obtained by ELISA method. Method: In this investigation, 50 children with Guillain-Barre syndr...

Passively acquired antibodies through colostrum will protect calves against etiological agents of neonatal calf diarrhea. Among them enteric diseases due to strains of Enterotoxigenic Escherichia coli (ETEC) are the most commonly occurring form of colibacillosis in newborn calves. Specific antibodies against whole ETEC cells and total immunoglobulin G in dam serum, colostrum and calf serum were...

Myelin proteolipid protein (PLP), the major protein of mammalian CNS myelin, is a member of the proteolipid gene family (pgf). It is an evolutionarily conserved polytopic integral membrane protein and a potential autoantigen in multiple sclerosis (MS). To analyze antibody recognition of PLP epitopes in situ, monoclonal antibodies (mAbs) specific for different regions of human PLP (50-69, 100-12...
