minicell

minicell

a bacterial ‘CELL’ that lacks a CHROMOSOME. It is formed from a MUTANT cell in which CELL DIVISION is aberrant, such that the SEPTUM forms towards one end of the cell, generating a small cell (‘minicell’) which has no chromosomal DNA. Minicells do not grow after they have formed, but they can be used to provide experimental TRANSCRIPTION and TRANSLATION systems if infected with DNA.

The outer surface of the minicell membrane is not only packed with gene silencing siRNA, but is also coated with antibodies, which lock onto (antigen) receptors on the tumour cells.

The first studies describing the antitumor immunotherapeutic properties of Salmonella enterica were conducted by Kurashige et al., using minicells (vesicles with no genomic DNA) obtained from Salmonella Typhimurium, and evaluated in two different murine models (sarcoma [74] and T-cell lymphoma [75]); they observed that the administration of these minicells restored macrophage activity in the tumor microenvironment, promoting tumor elimination.

The ability of miR-193a-3p to promote apoptosis was further demonstrated in MPM xenograft models when targeted by miR mimics delivered using EDV nanocells, bacterially-derived minicells that can be packaged with a variety of cargoes and be delivered to tumors via bispecific antibodies attached on surface [13].
