Dynamics of three MET antibody constructs (IgG1, IgG2, and IgG4) and the IgG4-MET antigen complex was investigated by creating their atomic models with an integrative experimental and computational approach. In particular, we used two-dimensional (2D) Electron Microscopy (EM) images, image class averaging, homology modeling, Rapidly exploring Random Tree (RRT) structure sampling, and fitting of...

An ELISA was applied to measure IgG sub-class antibodies to cow's milk beta-lactoglobulin (BLG), alpha-lactalbumin (ALA) and alpha-casein (AC) and to hen's egg ovalbumin (OA) in the sera of nineteen adult patients with milk intolerance causing either asthma, eczema or both. Results were compared with those of forty blood donors and twenty adult patients with either asthma or eczema due to inhal...

We report a case of a 71-year-old Filipino female who was admitted to the hospital for abdominal pain, vomiting and diarrhea of 8 days duration. The patient was found to have marked acute kidney injury (AKI), which required hemodialysis in the next 3 days. Extensive workup revealed hematuria, subnephrotic range proteinuria, elevated anti-nuclear antibody (ANA) and elevated total immunoglobulin ...

INTRODUCTION B cell-activating factor of the tumor necrosis factor family (BAFF) and a proliferation-inducing ligand (APRIL) play a crucial role in B cell development, survival, and antibody production. Here we analyzed the serum levels of BAFF and APRIL and their respective clinical associations in patients with an immunoglobulin (Ig) G4-related disease (IgG4-RD). METHODS We measured serum l...

A 63-year-old man was admitted to our department following a secondary medical examination. Blood tests showed high levels of liver enzymes, IgG, IgG4, and antinuclear antibody. Computed tomography showed tumors in the bilateral lower lobes of the lungs and pleural thickening. After pleural and liver biopsy procedures, he was conclusively diagnosed with IgG4-related lung pseudotumor and pleural...

Human antibody response to the Anopheles gambiae salivary protein gSG6 has recently emerged as a potentially useful tool for malaria epidemiological studies and for the evaluation of vector control interventions. However, the current understanding of the host immune response to mosquito salivary proteins and of the possible crosstalk with early response to Plasmodium parasites is still very lim...

background: lung carcinoma is a multiple type cancer comprising of small cell and non-small cell carcinomas (nsclc). for therapeutic and diagnostic purposes, serum monoclonal antibodies have been produced against lung cancer. objective: to charac-terize a murine monoclonal antibody (me3d11) reactive with human nsclc. methods: a murine monoclonal antibody (me3d11) reactive with human nsclc was s...

Cell surface molecules PD-L1 and CD47 are potent inhibitors of adaptive innate anti-cancer immunity. We sought to generate a safe, therapeutic, bispecific antibody specifically targeting, blocking both inhibitory activity. Novel anti-PDL-1 anti-CD47 antibodies with favorable activity, were humanized constructed into unique bi-specific intended for clinical use. Previous pre-clinical studies usi...

radiolabeled monoclonal antibodies, have created new innovations in diagnosis, research and therapy of disease in last 2 decades. one of the serious limitation of applications of radiolabeled antibodies in vivo is relatively low target to background activity. various strategies have been proposed to solve this problem including pre-targeting methods that was suggested in 1989. regarding importa...
