Intravenous and topical intranasal bevacizumab (Avastin) in hereditary hemorrhagic telangiectasia.

Current treatment of severe epistaxis in patients with hereditary hemorrhagic telangiectasia is not durable in reducing the frequency and severity of bleeds. Recent reports have demonstrated marked improvement of epistaxis with administration of either intravenous or topical bevacizumab. We present the long-term outcome of a patient who received repeated treatments of intravenous bevacizumab followed by maintenance intranasal bevacizumab.

Lentivirus-mediated expression of mutant MGMTP140K protects human CD34+ cells against the combined toxicity of O6-benzylguanine and 1,3-bis(2-chloroethyl)-nitrosourea or temozolomide.

Lentiviral vectors are capable of efficiently transducing nondividing and slowly dividing cells, including hematopoietic stem cells, resulting in stable integration and sustained transgene expression. We constructed human immunodeficiency virus type 1-based self-inactivating lentiviral vectors to express either wild-type or an O6-benzylguanine (O6-beG)-resistant mutant form of the human O6-alkylguanine-DNA methyltransferase (MGMT; DNA-O6-methylguanine:[protein]-L-cysteine S-methyltransferase, EC 2.1.

Immune Modulation in Cancer Patients After Adoptive Transfer of Anti-CD3/Anti-CD28-Costimulated T Cells-Phase I Clinical Trial.

Anti-CD3/anti-CD28 monoclonal antibody-coactivated T cells (COACTs) proliferate, secrete tumoricidal cytokines, and mediate non-major histocompatibility complex (MHC)-restricted cytotoxicity. This phase I study was done to determine the safety, maximum tolerated dose, technical limits of expansion, and modulation of immune functions in cancer patients given COACTs. Coactivated T cells were produced by stimulating peripheral blood mononuclear cells (PBMCs) with OKT3 anti-CD3 and 9.
