Lectin Pathway Enzyme MASP-2 and Downstream Complement Activation in COVID-19

open access: yesJournal of Innate Immunity, 2022
Mannose-binding lectin-associated serine protease 2 (MASP-2) is the main activator of the lectin complement pathway and has been suggested to be involved in the pathophysiology of coronavirus disease 2019 (COVID-19).

Determination of enzyme activities with the enzyme thermistor unit [PDF]

open access: yesFEBS Letters, 1979
Practically all enzyrnic reactions can be followed by calorimetry. Important advantages of this technique are that the optical properties of the sample do not interfere with the measurements and that no auxiliary enzymic reactions are required such as those leading to changes in optical absorption that can be followed spectrophotometrically.

Enzyme Kinetics by Isothermal Titration Calorimetry: Allostery, Inhibition, and Dynamics

open access: yesFrontiers in Molecular Biosciences, 2020
Isothermal titration calorimetry (ITC) involves accurately measuring the heat that is released or absorbed in real time when one solution is titrated into another. This technique is usually used to measure the thermodynamics of binding reactions. However,

Approximations and their consequences for dynamic modelling of signal transduction pathways [PDF]

open access: yes, 2007
Signal transduction is the process by which the cell converts one kind of signal or stimulus into another. This involves a sequence of biochemical reactions, carried out by proteins.

Enzyme activities in activated sludge flocs [PDF]

open access: yesApplied Microbiology and Biotechnology, 2007
This study quantified the activities of enzymes in extracellular polymeric substances (EPS) and in pellets. Seven commonly adopted extraction schemes were utilized to extract from aerobic flocs the contained EPS, which were further categorized into loosely bound (LB) and tightly bound (TB) fractions.

Halophilic enzyme activation induced by salts

open access: yesScientific Reports, 2011
Halophilic archea (halobacteriae) thrive in hypersaline environments, avoiding osmotic shock by increasing the ion concentration of their cytoplasm by up to 3–6 M.

Interactions between the endocrine and immune systems in locusts [PDF]

open access: yes, 2003
The prophenoloxidase cascade in the haemolymph of mature adult Locusta migratoria migratorioides (R & F) is activated in response to injection of laminarin, a -1,3 glucan.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.
