Vasoactive intestinal chemical sequence inhibits TNF-alpha-induced apoptotic events in acinar cells from nonobese diabetic mice submandibular glands.

Arthritis research & therapy · 2009

Study scale: We presented evidence to indicate that acinar cells isolated from submandibular glands of NOD mice with salivary dysfunction are more sensitive to TNF-α-induced apoptotic events than BALB/c control cells and that VIP prevents these effects.

Plain-language verified summary

Question

The aim of the present study was to analyse apoptotic events involving TNF-α/TNF-αR in isolated acini from NOD mice submandibular glands and to explore the ability of VIP to modulate these effects.

Methods

The role of apoptosis of secretory epithelium as a triggering factor of early dysfunction and autoimmune response has been explored in patients with Sjögren's syndrome and in the pre-diabetic NOD mouse model.

Scale or participants

We presented evidence to indicate that acinar cells isolated from submandibular glands of NOD mice with salivary dysfunction are more sensitive to TNF-α-induced apoptotic events than BALB/c control cells and that VIP prevents these effects.

Key findings

The role of apoptotic secretory epithelium as a pro-inflammatory triggering factor of exocrine dysfunction is currently explored in Sjogren's syndrome patients and in the nonobese diabetic (NOD) mouse model.

Limitations and uncertainty

Our conclusions are based on three main observations.
