Acquired dysfibrinogenemia caused by monoclonal production of immunoglobulin λ light chain

Haematologica, 2007
Disorders of fibrinogen are usually caused by genetic mutations that result in low protein levels (hypofibrinogenemia) or an abnormal molecule (dysfibrinogenemia). However, environmental and plasma factors can have an acquired effect on its expression or

Expression of combinatorial immunoglobulins in macrophages in the tumor microenvironment. [PDF]

PLoS ONE, 2018
Recent evidence indicates the presence of macrophage subpopulations that express the TCRαβ in chronic inflammatory diseases such as tuberculosis and atherosclerosis and in the tumor microenvironment.

Interaction of a single mode field cavity with the 1D XY model: Energy spectrum [PDF]

Journal of Physics: Conference Series 682 (2016) 012032, 2016
In this work we use the fundamental in quantum optics Jaynes-Cummings model to study the response of spin $\tfrac12$ chain to a single mode of a laser light falling on one of the spins, a focused interaction model between the light and the spin chain. For the spin-spin interaction along the chain we use the XY model. We report here the exact analytical

Immunoglobulin Light Chains Generate Hydrogen Peroxide [PDF]

Journal of the American Society of Nephrology, 2007
As low molecular weight proteins, restriction from glomerular filtration is minimized, permitting significant amounts of Ig light chains to be endocytosed into the proximal tubule epithelium, particularly in plasma cell dyscrasias. Recent studies have shown that this effect of concentrating light chains within the proximal tubule alters cell function ...

Positive feedback loop between MAPK and aquaporin 7 regulates autophagy and apoptosis induced by palmitate in RIN‐m5f cells

FEBS Open Bio, EarlyView.
T2DM is characterized by peripheral blood insulin resistance and progressive pancreatic β‐cell dysfunction. Here, we showed that AQP7, the only aquaglyceroporin protein, regulates autophagy and apoptosis in pancreatic β‐cells. We propose the existence of a positive feedback loop between MAPK signaling and AQP7 that regulates autophagy and apoptosis in ...

CSF cytokine, chemokine and injury biomarker profile of glial fibrillary acidic protein (GFAP) autoimmunity

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Defining the CSF cytokine/chemokine and injury biomarker signature of glial fibrillary acidic protein (GFAP) autoimmunity can inform immunopathogenesis. CSF GFAP‐IgG‐positive samples (N = 98) were tested for 17 cytokines/chemokines, neurofilament light chain (NfL), and GFAP (ELLA, Bio‐Techne).

Recommendations for use of free light chain assay in monoclonal gammopathies [PDF]

Journal of Medical Biochemistry, 2010
The serum immunoglobulin free light chain assay measures levels of free k and l immunoglobulin light chains. There are three major indications for the free light chain assay in the evaluation and management of multiple myeloma and related plasma cell ...

Cryo-EM structure of cardiac amyloid fibrils from an immunoglobulin light chain AL amyloidosis patient

Nature Communications, 2019
Immunoglobulin Light Chain Amyloidosis (AL) is the most common systemic amyloidosis occurring in Western countries. Here the authors present the 4.0 Å cryo-EM structure of light chain AL55 fibrils that were isolated from the heart of an AL systemic ...

Risk factors for venous thromboembolism in immunoglobulin light chain amyloidosis

Haematologica, 2016
Patients with immunoglobulin light chain amyloidosis are at risk for both thrombotic and bleeding complications. While the hemostatic defects have been extensively studied, less is known about thrombotic complications in this disease.

If it does not help, it might hurt: Pharmacodynamics of a second IVIg course in Guillain–Barré syndrome

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Objectives Intravenous immunoglobulin (IVIg) is an effective treatment for Guillain–Barré syndrome (GBS), but recovery varies between patients. This study aims to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of a single and a second IVIg dose (SID) in patients with GBS.
