This is known as autocrine signalling.

Other types of cell signaling include paracrine signalling and autocrine signalling.

This leads to the production of more TNF-alpha, its release, and binding to the receptors on the cells that released it (autocrine signalling).

Effects varies based on the endocannabinoid molecule: 2-AG was found to act on presynaptic CB receptors to mediate retrograde short-term depression following activation of L-type calcium currents, while anandamide was synthesized after mGluR5 activation and triggered autocrine signalling that induced long-term depression.
