An active mitochondrial biogenesis occurs during dendritic cell differentiation.

Dendritic cells (DC) are sentinels of the immune system deriving from circulating monocyte precursors recruited to sites of inflammation. In a previous report (Del Prete et al., 2008) we showed that, after differentiation, DC exhibited increased number of condensed mitochondria and dynamic changes in their energy metabolism.

Comparative proteomic analysis of four Bacillus clausii strains: proteomic expression signature distinguishes protein profile of the strains.

A comparative proteomic approach, using two dimensional gel electrophoresis and mass spectrometry, has been developed to compare and elucidate the differences among the cellular proteomes of four closely related isogenic O/C, SIN, N/R and T, B. clausii strains during both exponential and stationary phases of growth. Image analysis of the electropherograms reveals a high degree of concordance among the four proteomes, some proteins result, however, differently expressed.
