T Cells Found Living in Healthy Brains

Contrary to long-standing beliefs, T cells—key immune cells—have been discovered in the healthy brains of both mice and humans. These cells, previously thought to only enter the brain during disease, were most concentrated in a region that regulates hunger and thirst.

Female Hormones Trigger Pain Relief via Immune Cells

Scientists have discovered that female hormones like estrogen and progesterone can trigger immune cells near the spinal cord to release natural opioids, easing pain before it reaches the brain. These immune cells, known as T regulatory cells (T-regs), are located in the meninges and produce the painkilling molecule enkephalin in response to hormonal signals.

Early Immune Cell Changes May Predict Multiple Sclerosis Onset

A new study shows that CD8-positive T cells play a significant role in the early stages of multiple sclerosis (MS). By studying identical twins where one twin has MS and the other is asymptomatic, researchers found that CD8 T cells exhibit specific changes before symptoms arise, including increased migration and inflammation promotion.

T Cells May Be The Living Anti-Aging Elixir

Researchers found that T cells can be genetically reprogrammed to target and eliminate senescent cells, which contribute to aging-related diseases. By using CAR (chimeric antigen receptor) T cells in mice, they achieved significant health improvements including lower body weight, enhanced metabolism, and increased physical activity.

3D Model Reveals T Cell Role in Alzheimer’s Progression

Researchers developed a 3D cellular model to study the interactions between brain cells and immune cells in Alzheimer's disease. This new model, based on advanced microfluidic technology, demonstrates that specific immune cells, CT8+ T Cells, amplify Alzheimer's pathology when they infiltrate the brain.

Immune’s Surprise Role: Regulatory T Cells Impact Mood and Memory

Regulatory T cells (Tregs), usually tasked with immune system regulation, might also play a pivotal role in mood stabilization. Controlled by the transcription factor Foxp3, any decrease in its expression has been linked to major depressive disorders.
