Mitochondria contain their own circular genome of alpha-proteobacterial origin, the mitochondrial DNA (mtDNA) organized into nucleoids in the matrix (Fig. 1). High resolution electron micrographs of mouse and human nucleoids revealed that most of them are located inside mitochondrial tubes. One ...
Smaller mitochondrial bodies released into the blood, termed “mitovesicles”, contain DNA, RNA, proteins and lipids (Abels and Breakefield, 2016) through which they convey mitochondrial damage-associated molecular patterns (mtDAMPs) that alter the metabolic response of recipient cells (Grazioli and ...
Mitochondria and bacteria also harbour circular DNA containing CpG-rich motifs. Furthermore, gram- negative bacteria and mitochondria both have a double phospho- lipid membrane layer—the inner and outer membrane. The inner membrane encapsulates the cytosol of gram-negative bacteria and the matrix of...
The preferable antigen delivery profile accompanied by sufficient adjuvants favors vaccine efficiency. Mitochondria, which feature prokaryotic characteristics and contain various damage-associated molecular patterns (DAMPs), are easily taken up by phagoc
mtDNA is a double-stranded circular structure (Fig.1c). Each mitochondrion harbors 10–10,000 copies of mtDNA, in contrast to the nuclear DNA (nDNA) which contains only two copies per cell. The mitochondrial genomes are organized with factors such as mitochondrial transcription factor A (TFAM...
Mitochondria also contain in their matrix single or double circular and double-stranded DNA molecules called mt DNA and also the 55S ribosomes, called mitoribosomes. Since mitochondria can synthesize 10 percent of their proteins in their own protein-synthetic machinery, they are considered assemi-...
They also contain a circular genome, mitochondrial DNA (mtDNA), that has been reduced during evolution through gene transfer to the nucleus. mtDNA is organized into discrete nucleoids in the matrix. Interestingly, the closest relatives of many mtDNA-modifying enzymes, such as mtDNA polymerase, are...
