Project description:We discovered “runner” plasma, collected from voluntarily running mice, infused into sedentary mice recapitulates the cellular and functional benefits of exercise on the adult brain. Importantly, runner plasma reduces baseline neuroinflammatory gene expression and experimentally induced brain inflammation. Plasma proteomic analysis revealed a striking increase in complement cascade inhibitors including clusterin (CLU), which is facilitating the anti-inflammatory effects of runner plasma. Intravenously injected CLU strongly binds to brain endothelial cells reducing their inflammatory gene expression in an acute model of brain inflammation and in Alzheimer’s disease model mice. These findings demonstrate the existence of anti-inflammatory “exercise factors” that are transferrable, target the cerebrovasculature and benefit the brain.

Project description:Physical exercise seems universally beneficial to human and animal health, slowing cognitive aging and neurodegeneration. Cognitive benefits are tied to increased plasticity and reduced inflammation within the hippocampus, yet little is known about the factors and mechanisms mediating these effects.

Importantly, runner plasma reduces baseline neuroinflammatory gene expression and experimentally induced brain inflammation.

Intravenously injected CLU strongly binds to brain endothelial cells reducing their inflammatory gene expression in an acute model of brain inflammation and in Alzheimer’s disease model mice. Cognitively impaired patients participating in structured exercise for 6 months showed improved cognition and higher plasma clusterin levels. These findings demonstrate the existence of anti-inflammatory “exercise factors” that are transferrable, target the cerebrovasculature and benefit the brain, and are present in humans engaging in exercise.

Project description:Physical exercise seems universally beneficial to human and animal health, slowing cognitive aging and neurodegeneration. Cognitive benefits are tied to increased plasticity and reduced inflammation within the hippocampus, yet little is known about the factors and mechanisms mediating these effects. We discovered that “runner” plasma, collected from voluntarily running mice and infused into sedentary mice, reduces baseline neuroinflammatory gene expression and experimentally induced brain inflammation. Plasma proteomic analysis revealed a concerted increase in complement cascade inhibitors including clusterin (CLU), a central protein for the anti-inflammatory effects of runner plasma. Intravenously injected CLU strongly binds to brain endothelial cells reducing their inflammatory gene expression in an acute model of brain inflammation and in an Alzheimer’s disease mouse model. Cognitively impaired patients participating in structured exercise for 6 months had higher plasma clusterin levels. These findings demonstrate the existence of anti-inflammatory “exercise factors” that are transferrable, target the cerebrovasculature and benefit the brain, and are present in humans engaging in exercise.

Project description:Physical exercise is generally beneficial to all aspects of human and animal health, slowing cognitive ageing and neurodegeneration1. The cognitive benefits of physical exercise are tied to an increased plasticity and reduced inflammation within the hippocampus2-4, yet little is known about the factors and mechanisms that mediate these effects. Here we show that 'runner plasma', collected from voluntarily running mice and infused into sedentary mice, reduces baseline neuroinflammatory gene expression and experimentally induced brain inflammation. Plasma proteomic analysis revealed a concerted increase in complement cascade inhibitors including clusterin (CLU). Intravenously injected CLU binds to brain endothelial cells and reduces neuroinflammatory gene expression in a mouse model of acute brain inflammation and a mouse model of Alzheimer's disease. Patients with cognitive impairment who participated in structured exercise for 6 months had higher plasma levels of CLU. These findings demonstrate the existence of anti-inflammatory exercise factors that are transferrable, target the cerebrovasculature and benefit the brain, and are present in humans who engage in exercise.

Project description:The conserved human secreted glycoprotein Clusterin (aka Apolipoprotein-J, ApoJ) is an abundant component of body fluids such as blood plasma and cerebrospinal fluid. Clusterin is thought to function as an extracellular molecular chaperone stabilizing misfolded proteins in solution. In addition, Clusterin forms lipoprotein complexes and fractions with HDL particles in plasma. Variants of the Clusterin gene constitute the third most important genetic risk factor for late-onset Alzheimer's disease. To better understand its structure and functions, the crystal structure of a mutant form of Clusterin was determined. In order to validate the structural data, hydrogen-deuterium exchange kinetics followed by pepsin proteolysis and mass spectrometry analysis of recombinant mutant and wildtype protein were performed (Part 1 of the deposited data). Based on the structure, rational mutants were designed and subjected to functional tests such as chaperone activity, cellular uptake and receptor binding and lipoprotein complex formation. In order to probe the conformation of Clusterin in the lipoprotein complex, free and lipid-bound protein were subjected to limited proteolysis with chymotrypsin and the resultant fragments analyzed by LC/MS proteomics (Part 2 of the deposited data).

Project description:Clusterin has been indicated to protect human retinal pigment epithelial (RPE) cells from oxidative stress-induced apoptosis. This study was conducted to identify aberrantly expressed microRNAs (miRNAs) downstream clusterin in RPE cells.

Project description:Plasma collected from mice with FIA were pooled, and 0.3 ml was injected intravenously into 6-week-old naïve SJL mice on days 0 and 2. Synovial antigen array profiling of plasma from the arthritic recipient mice demonstrated autoreactive B-cell responses against peptides representing native fibrinogen and citrullinated fibrinogen, and further epitope spreading resulting in additional targeting of fibronectin, collagen type V, cartilage gp39, and clusterin. Custom-spotted protein slides were probed with plasma samples from individual mice. Four slides were probed with plasma derived from naïve mice and four slides were probed with plasma derived from mice injected with FIA plasma.

Project description:Profiling of circulating miRNAs before, 60 mins, 1day and 3 days after an acute resistance exercise. Three subjects performed an acute resistance exercise. The resistance exercise consisted of two consecutive exercises (bench press and bilateral leg press), consisting of five sets of 10 repetitions at 70% of 1 RM. The subjects were allowed to rest for 1 min between each set and exercise. The subjects were instructed to lift and lower the load at a constant velocity, taking about 2 s for each repetition. If the load became too heavy, the subject was assisted. The range of motion in each exercise was from 90° to 0° (0° at full extension). Blood samples were taken before, 60 mins, 1day and 3days after the exercise.
