Autoimmune myocarditis develops after the presentation of heart-specific antigens to autoaggressive CD4+ T cells and after inflammation has infiltrated the tissues. To shed light on global changes in the gene expression of autoimmune myocarditis and to gain further insight into the molecular mechanisms underlying the genesis of myocarditis, we conducted a comprehensive microarray analysis of mRNA using an experimental mouse autoimmune myocarditis model via immunization with α-myosin heavy chain-derived peptides. Of over 39,000 transcripts on a high density oligonucleotide microarray, 466 were under-expressed and 241 over-expressed by ≥ 1.5-fold compared with the controls in BALB/C mouse with autoimmune myocarditis. In this paper, we list the top 50 up-regulated genes related to the immune response. These altered genes encode for leukocyte-specific markers and receptors, the histocompatibility complex, cytokines/receptors, chemokines/receptors, adhesion molecules, components of the complement cascade, and signal transduction-related molecules. Interestingly, matrix metalloproteinases (MMPs) such as MMP-3 and MMP-9 were up-regulated, as further revealed by the reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry assays. This indicates that MMPs may act as major regulators of the cytokine profile. Together, these findings provide new insight into the molecular events associated with the mechanism of the autoimmune genesis of myocarditis.

Growing number of studies reveal that the brain neural network plays significant role in the short-term and long-term regulation of the cardiovascular functions. The neurons involved in the complex neurogenic control of the cardiovascular system use classical neurotransmitters and nonconventional mediators such as peptides (angiotensin II, vasopressin, natriuretic peptides, endothelins, opioids, cytokines), steroids, ouabaine-like factors and gaseous compounds. Among them the neuropeptides form a group of substances arising significant interest. Thanks to wide distribution of peptidergic neurons in the central nervous system, location of peptide receptors on neurons and glial cells, versatile but frequently overlapping mechanisms of activation of the intracellular processes the neuropeptides play significant role in short-term and long-term regulation of excitability and remodeling of the neurons. In several instances they modulate effects of the classical transmitting systems involved in regulation blood pressure, heart rate, water-electrolyte balance, metabolism, stress, pain, mood and memory. Prolonged activation or inhibition of specific neuropeptide pathways frequently results in long-lasting disorders of several regulatory systems. In this review this is exemplified by overactivity of angiotensin II, vasopressin and cytokines in the brain during hypertension, heart failure and stress. Multifarious actions of angiotensin II and vasopressin, and their mutual interaction with cytokines make of these neuropeptides excellent candidates for the compounds responsible for long-term resetting of the central cardiovascular control, and forming a link between the cardiovascular diseases, stress and mood disorders.
