Abstract:
The mechanisms connecting obesity to pancreatic cancer progression remain poorly defined. A new study reveals that extracellular vesicles from visceral adipose tissue reprogram immune cells through a cathepsin A-pseudouridine-mast cell axis, uncovering how obesity drives immune evasion and resistance to checkpoint blockade therapy in pancreatic cancer.

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Autocrine Signaling
52.0K
Autocrine signaling is one of the many signaling mechanisms that function inside multicellular organisms to carry out intercellular communication. In this type of signaling mechanism, the same cell that secretes an extracellular signaling molecule also expresses the receptors to bind and respond to that signaling molecule.
