holocrine secretion

Holocrine secretion is the most damaging type of secretion, with merocrine secretion being the least damaging and apocrine secretion falling in between.

The cytosolic α-LTX precursor molecule is released from the cell by means of holocrine secretion where it ends up in the venom gland of the spider.

Apocrine secretion is less damaging to the gland than holocrine secretion (which destroys a cell) but more damaging than merocrine secretion (exocytosis).

Holocrine secretions are produced in the cytoplasm of the cell and released by the rupture of the plasma membrane, which destroys the cell and results in the secretion of the product into the lumen.
