Fc region binding peptide conjugated with attenuated cationic amphiphilic lytic L17E trimer [FcB(L17E)3] was designed for immunoglobulin G (IgG) delivery into cells. Particle-like liquid droplets were generated by mixing Alexa Fluor 488 labeled IgG (Alexa488-IgG) FcB(L17E)3. Droplet contact the cellular membrane led to spontaneous influx and distribution of Alexa488-IgG throughout cells in seru...

OBJECTIVE To assess the impact of immunosuppressive therapy with cyclophosphamide (CYC) and rituximab (RTX) on serum immunoglobulin (Ig) concentrations and B lymphocyte counts in patients with ANCA-associated vasculitides (AAVs). METHODS Retrospective analysis of Ig concentrations and peripheral B cell counts in 55 AAV patients. RESULTS CYC treatment resulted in a decrease in Ig levels (med...

Background: Scleroderma is a chronic systemic disorder that affects the connective tissues. It is characterized by several immune manifestations, inflammation, vascular damage, and fibrosis. Some of the viral infections with complex mechanisms are involved in the development and progression of many autoimmune diseases, such as scleroderma. The present study aimed to investigate the serological ...

The objective of this study was to determine the effects of supplemented selenium (Se) on plasma cortisol, red blood cell glutathione peroxidase activity (RBC GSH-PX-1), concentration of immunoglobulin G (IgG) and body weight in pneumonic suckling calves. Ten Holstein suckling male calves were randomly allocated to two groups and fed either unsupplemented milk (control) or with milk supplemente...

Levels of rotavirus-specific immunoglobulin G (IgG), IgA, IgM, and secretory immunoglobulin in maternal and cord serum, colostrum and milk, and infants' stools were measured by enzyme-linked immunosorbent assay in 92 mothers and their infants. Although antirotaviral IgG, IgA, and secretory immunoglobulin were present in most maternal sera, only IgG crossed the placenta. All samples of colostrum...

Papadatos, C., Papaevangelou, G. J., Alexiou, D., and Mendris, J. (1970). Archives of Disease in Childhood, 45, 570. Serum immunoglobulin G levels in small-for-dates newborn babies. Immunoglobulin G levels have been studied in 47 small-for-dates (SFD) and 197 singieton babies of normal birthweight for their gestational age. The IgG values in the SFD babies were below those expected for the norm...

Polyclonal antibodies against kappa light chain are used to diagnose diseases producing free light chain. The kappa and lambda light chains are products of immunoglobulin synthesis and released into the circulation in minor amounts such as serum, cerebrospinal fluid, urine and synovial fluid in normal condition. The purpose of this study was the production and purification of polyclonal immunog...

Having a theoretical understanding of the orientation of immunoglobulin on an immobilized solid surface is important in biomedical pathogen-detecting systems and cellular analysis. Despite the stable adsorption of immunoglobulin on a polystyrene (PS) surface that has been applied in many kinds of immunoassays, there are many uncertainties in antibody-based clinical and biological experimental m...

The aim of this study was to determine whether latent viral infection is associated with idiopathic pulmonary fibrosis (IPF), an interstitial lung disease whose aetiology remains to be elucidated. Cytomegalovirus (CMV) immunoglobulin G (IgG) and complement fixation (CF), Epstein-Barr (EB) viral capsid antigen (VCA) IgG, herpes simplex virus (HSV) IgG, adenovirus CF, and parainfluenza 3 virus ha...
