The scientific development of immunotherapies and radioimmunotherapies of cancer began more than four decades ago. Over time, it has become apparent that the choice of target antigen, immunogenicity of antibodies, length of antibody half-life, ability of antibodies to recruit immune effector functions, decision on conjugation of antibodies to toxins or radionuclides and antibody manufacturing are critical com Read More

Peptides, proteins, and nucleotides or DNA fragments are the new generation of drugs. They are becoming attractive owing to the fast development of biotechnology. The admnistration of such molecules, however, may be a problem as sensitivity to temperature, instability at some physiological pH values, short plasma half-life, and high molecular dimension, which hinders the diffusive transport, make, at the momen Read More

The number of diseases found to be associated with defects of the mitochondrial genome has grown significantly over the last decade. Despite major advances in understanding mtDNA defects at the genetic and biochemical level, there is no satisfactory treatment for the vast majority of patients available. This is largely due to the fact that almost all mitochondrial DNA defects involve the final common pathway of oxidativ Read More

The number of therapeutic proteins successfully produced in plants is steadily increasing and is expected to grow even more rapidly in the future. Most therapeutic proteins are glycoproteins and N-glycosylation is often essential for their stability, folding and biological activity. Recombinant glycoproteins of mammalian origin expressed in transgenic plants largely retain their biological activity. However, plants are not ideal for Read More

Actinomycetes are gram-positive bacteria and commercially important microorganisms. They are producers of approximately two thirds of all bioactive compounds known and they produce a great variety of compounds which have clinical application on the basis of their activity against different kinds of organisms and cells as antibacterial (macrolides, avermectins), antitumor (anthracyclines, angucyclines, aureolic acid Read More
