Three types of PPARs have been identified: alpha, gamma, and delta (beta):
- α (alpha) - expressed in liver, kidney, heart, muscle, adipose tissue, and others
- β/δ (beta/delta) - expressed in many tissues but markedly in brain, adipose tissue, and skin
- γ (gamma) - although transcribed by the same gene, this PPAR through alternative splicing is expressed in three forms:
- γ1 - expressed in virtually all tissues, including heart, muscle, colon, kidney, pancreas, and spleen
- γ2 - expressed mainly in adipose tissue (30 amino acids longer)
- γ3 - expressed in macrophages, large intestine, white adipose tissue.

Famous quotes containing the words tissue and/or distribution:
“Whether or not his newspaper and a set of senses reduced to five are the main sources of the so-called “real life” of the so- called average man, one thing is fortunately certain: namely, that the average man himself is but a piece of fiction, a tissue of statistics.”
—Vladimir Nabokov (1899–1977)
“There is the illusion of time, which is very deep; who has disposed of it? Mor come to the conviction that what seems the succession of thought is only the distribution of wholes into causal series.”
—Ralph Waldo Emerson (1803–1882)
