Minicells or achromosomal cells
Minicells are achromosomal cells that are products of aberrant cell division, and contain RNA and protein, but little or no chromosomal DNA. Minicells are capable of plasmid-directed synthesis. Early descriptions of minicells include those of Adler et al., 'Genetic control of cell division in bacteria' (Science, 1966), and Adler et al. 'Miniature Escherichia coli cells deficient in DNA', (PNAS, 1967). However, discovery of the production of minicells can arguably be traced to the 1930's (Frazer and Curtiss III, 'Production, Properties and Utility of Bacterial Minicells', (Curr. Top. Microbiol. Immunol., 1975).
Prokaryotic (a.k.a. eubacterial) minicells have been used to produce various eubacterial proteins.
Interesting features and Open issues
- no ability to replicate or to cause infection.
- carry a normal component of bacterial proteins and membrane components.
- can be designed to contain any protein and/or plasmid DNA found in the parent strain of E. coli used to produce them
- how long the minicells are active ?
- what is the best way to isolate them ?
- Would minicells be a good chassis for biological engineered devices ?
