Safety, pharmacokinetics, and pharmacodynamics of TV-1380, a novel mutated butyrylcholinesterase treatment for cocaine addiction, after single and multiple intramuscular injections in healthy subjects.

Human plasma butyrylcholinesterase (BChE) contributes to cocaine metabolism and has been considered for use in treating cocaine addiction and cocaine overdose. TV-1380 is a recombinant protein composed of the mature form of human serum albumin fused at its amino terminus to the carboxy-terminus of a truncated and mutated BChE. In preclinical studies, TV-1380 has been shown to rapidly eliminate cocaine in the plasma thus forestalling entry of cocaine into the brain and heart.

Mutation analysis of the entire keratin 5 and 14 genes in patients with epidermolysis bullosa simplex and identification of novel mutations.

Epidermolysis bullosa simplex is a group of blistering skin disorders caused by defects in one of the keratin genes, KRT5 and KRT14. Previously reported KRT5 and KRT14 mutations are clustered in several hotspots, namely the rod ends of the 1A and 2B domains and in the non-helical linker region L12. Therefore, genomic KRT5 and KRT14 mutation analysis was initially limited to these hotspots.

Tumor-targeted immune complex formation: effects on myeloid cell activation and tumor-directed immune cell migration.

The effectiveness of cellular immunotherapy of solid tumors is often hampered by the lack of specific infiltration of immune effector cells into the tumor mass. Therefore, we studied the potential of tumor antigen-specific antibodies to elicit tumor-specific myeloid cell activation, to induce or enhance tumor infiltration by immune cells. To this end, we developed an in vitro model system using the human myeloid cell line MonoMac-6.

Partial revertant mosaicism of keratin 14 in a patient with recessive epidermolysis bullosa simplex.

A patient with recessive epidermolysis bullosa simplex due to a previously described homozygous KRT14 1842-2A-->C splice-site mutation was re-examined, because we unexpectedly found signs of revertant mosaicism. The germline mutation resulted in different aberrant transcripts containing premature termination codons, all leading to truncated keratin 14 proteins. Basal keratinocytes in skin and in culture completely lacked keratin 14 and intermediate filaments.
