LE cells

Either pinching or pinning the siphon decreased the threshold of the LE cells firing and enhanced soma excitability.

These LE cells display increasing discharge to increasing pressures, with maximal activation by crushing or tearing stimuli that cause tissue injury.

Many of these have focused on mechanosensory neurons innervating the siphon and having their somata (bulbous end) in the abdominal ganglion (LE cells).

Simplest classification tree: SLE is diagnosed if a person has an immunologic disorder (anti-DNA antibody, anti-Smith antibody, false positive syphilis test, or LE cells) or malar rash.

The lupus erythematosus (LE) cell test was commonly used for diagnosis, but it is no longer used because the LE cells are only found in 50-75% of SLE cases, and they are also found in some people with rheumatoid arthritis, scleroderma, and drug sensitivities.
