The Discovery of Cellular Immunity in the Atherosclerotic Plaque [History of Discovery]
Hansson, G. K., Jonasson, L. It is now generally accepted that atherosclerosis is an inflammatory/immune disease triggered by LDL accumulation in the artery wall. When discovering T cells and the molecular components of a cellular immune response, we proposed that atherosclerosis is an inflammatory process with an autoimmune component. This notion was met with general skepticism but has gained support from experimental and clinical studies. Here we describe some of the early studies that helped developing this concept.

Origin of Cardiac Fibroblasts and the Role of Periostin [Reviews]
Snider, P., Standley, K. N., Wang, J., Azhar, M., Doetschman, T., Conway, S. J. Abstract: Cardiac fibroblasts are the most populous nonmyocyte cell type within the mature heart and are required for extracellular matrix synthesis and deposition, generation of the cardiac skeleton, and to electrically insulate the atria from the ventricles. Significantly, cardiac fibroblasts have also been shown to play an important role in cardiomyocyte growth and expansion of the ventricular chambers during heart development. Although there are currently no cardiac fibroblast-restricted molecular markers, it is generally envisaged that the majority of the cardiac fibroblasts are derived from the proepicardium via epithelial-to-mesenchymal transformation. However, still relatively little is known about when and where the cardiac fibroblasts cells are generated, the lineage of each cell, and how cardiac fibroblasts move to reside in their final position throughout all four cardiac chambers. In this review, we summarize the present understanding regarding the function of Periostin, a useful marker of the noncardiomyocyte lineages, and its role during cardiac morphogenesis. Characterization of the cardiac fibroblast lineage and identification of the signals that maintain, expand and regulate their differentiation will be required to improve our understanding of cardiac function in both normal and pathophysiological states.
Smooth Muscle Cell {alpha}2{delta}-1 Subunits Are Essential for Vasoregulation by CaV1.2 Channels [Cellular Biology]
Bannister, J. P., Adebiyi, A., Zhao, G., Narayanan, D., Thomas, C. M., Feng, J. Y., Jaggar, J. H. Rationale: Voltage-dependent L-type (CaV1.2) Ca2+ channels are a heteromeric complex formed from pore-forming 1 and auxiliary 2 and β subunits. CaV1.2 channels are the principal Ca2+ influx pathway in arterial myocytes and regulate multiple physiological functions, including contraction. The macromolecular composition of arterial myocyte CaV1.2 channels remains poorly understood, with no studies having examined the molecular identity or physiological functions of 2 subunits. Objective: We investigated the functional significance of 2 subunits in myocytes of resistance-size (100 to 200 µm diameter) cerebral arteries. Methods and Results: 2-1 was the only 2 isoform expressed in cerebral artery myocytes. Pregabalin, an 2-1/-2 ligand, and an 2-1 antibody, inhibited CaV1.2 currents in isolated myocytes. Acute pregabalin application reversibly dilated pressurized arteries. Using a novel application of surface biotinylation, data indicated that >95% of CaV1.2 1 and 2-1 subunits were present in the arterial myocyte plasma membrane. 2-1 knockdown using short hairpin RNA reduced plasma membrane-localized CaV1.2 1 subunits, caused a corresponding elevation in cytosolic CaV1.2 1 subunits, decreased intracellular Ca2+ concentration, inhibited pressure-induced vasoconstriction ("myogenic tone"), and attenuated pregabalin-induced vasodilation. Prolonged (24-hour) pregabalin exposure did not alter total 2-1 or CaV1.2 1 proteins but decreased plasma membrane expression of each subunit, which reduced myogenic tone. Conclusions: 2-1 is essential for plasma membrane expression of arterial myocyte CaV1.2 1 subunits. 2-1 targeting can block CaV1.2 channels directly and inhibit surface expression of CaV1.2 1 subunits, leading to vasodilation. These data identify 2-1 as a novel molecular target in arterial myocytes, the manipulation of which regulates contractility.
