Chimeric receptor genes suitable for endowing lymphocytes with antibody-type specificity include a first gene segment encoding a single-chain Fv domain of a specific antibody and a second gene segment encoding all or part of the transmembrane and cytoplasmic domains, and optionally the extracellular domain, of an immune cell-triggering molecule. The chimeric receptor gene, when transfected to immune cells, expresses the antibody-recognition site and the immune cell-triggering moiety into one continuous chain. The transformed lymphocytes are useful in therapeutic treatment methods.

Described are devices and methods for treating degenerative, congestive heart disease and related valvular dysfunction. Percutaneous and minimally invasive surgical tensioning structures offer devices that mitigate changes in the ventricular structure (i.e., remodeling) and deterioration of global left ventricular performance related to tissue damage precipitating from ischemia, acute myocardial infarction (AMI) or other abnormalities.
