In vitro, ICD has been found to be associated with the spatiotemporally defined emission of danger signals such as surface exposed calreticulin (CRT) or heat shock protein 90 (HSP90), secreted ATP and released TLR4 agonists like HMGB1 or HSP70. Moreover, recently it has emerged that ICD may also be associated with a "viral response-like chemokine signature (VCS)" capable of acting as both 'find me' signal (for granulocytic myeloid cells) and 'keep away' signal (for immature monocytic myeloid cells) - further details of this paradigm are under investigation.
