🧪 A quick look behind the scenes. This 30 second clip condenses 25 minutes of prep for a metabolism assay on human brain cells ( #microglia ). Careful pipetting, clean technique, and lots of repetition. This is where the data begins.

🧪 Neuron-derived extracellular vesicles carry tau and inflammation signals after impacts. We are validating these as potential risk markers for athletes and exploring how they may spread pathology.

🩸 New #TBI biomarker signal
EV-GFAP in blood rises after TBI and relates to CT findings, flagging acute injury. Other EV markers were less helpful here, and plasma #GFAP still works well. We need more studies to learn when EVs add value for patients.

Repetitive concussions can harm brain function even without overt cell loss 🧠
New work in mice shows that repeat hits activate microglia, which then eat away at excitatory synaptic inputs. Learning and memory suffer, despite no obvious cell death or bruising.

🧠It's important to understand how #CTE is different to other #brain diseases. In CTE, tau builds up around small blood vessels at the depths of cortical sulci, often in layers II and III. In #Alzheimers, tau tracks a different path and sits alongside amyloid plaques.

🧠 Every #brain is different. With repetitive head impacts, wiring can be damaged and symptoms can appear. #CTE is diagnosed after death, but two clinical patterns are often discussed in life: a faster behavioural pattern and a slower #dementia like pattern.

#Microglia help explain why some people struggle cognitively after #TBI. Timing matters. Support early clean up, prevent long term overdrive, and protect synapses. Targeting microglia with the right therapy at the right time could change outcomes.
#BrainInjury #Science 🧪

#Microglia also shape synapses, the connections that carry thoughts. After #TBI they may prune too much or release signals that destabilise these links, decreasing spine density and weakening brain circuits, especially in the hippocampus.
#science #Braininjury 🧪

After #concussion, #inflammation aids clean up and injury resolution. If #microglia stay pro inflammatory for months or years, they keep releasing molecules that disrupt circuits, worsen blood #brain barrier leaks, and recruit more immune cells, prolonging symptoms.
#BrainInjury #TBI #Science 🧪
October 23, 2025 at 9:05 AM
Following #TBI, stress signals such as oxidative stress, calcium overload, and inflammatory signalling can push vulnerable neurons toward cell death. #Microglia may fuel this cascade, linking early injury to later memory issues.
#Neuroscience #Braininjury #Science 🧪

Inflammation is a double-edged sword.
Microglia patrol the brain. After #TBI they rush in, clear debris, and start repairs. Helpful inflammation can turn excessive, which then amplifies damage and impairs cognition. Balancing this response could be key.
#Braininjury #Concussion #Science 🧪

🧠 After a head injury, thinking and memory can slip not only from the initial hit but also from how the brain’s immune cells called microglia respond over hours, days, and months. They can help OR they can prolong problems that affect cognition.
