Cells transfected with an apoptosis-inhibiting gene or vector, such as a triple mutant Bcl-2 gene, can survive longer in culture, resulting in extension of the state and yield of protein biosynthesis. Such transfected cells exhibit maximal cell densities that equal or exceed the maximal density achieved by the parent cell lines. Transfected cells can also be pre-adapted for growth in serum-free medium, greatly decreasing the time required to obtain protein production in serum-free medium. In certain methods, the pre-adapted cells can be used for protein production following transformation under serum-free conditions. The method preferably involves eukaryotic cells, more preferably mammalian cells.Type: ApplicationFiled: November 2, 2011Publication date: April 12, 2012Applicant: IMMUNOMEDICS, INC.Inventors: David M.

Patent number: 8153425Abstract: Methods are provided for the production of dendritic cells from monocytes that have been incubated at a temperature of 1° C.-34° C. for a period of approximately 6 to 96 hours from the time they are isolated from a subject. After the incubation period, the monocytes can then be induced to differentiate into dendritic cells. Mature dendritic cells made by the methods of the invention have increased levels of one or more of CD80, CD83, CD86, MHC class I molecules, or MHC class II molecules as compared to mature dendritic cells prepared from monocytes that have not been held at 1° C.-34° C. for at least 6 hours from the time they were isolated from a subject. Dendritic cells made by the methods of the invention are useful for the preparation of vaccines and for the stimulation of T cells.Type: GrantFiled: April 7, 2006Date of Patent: April 10, 2012Assignee: Argos Therapeutics, Inc.Inventors: Rebecca Pogue-Caley, Tamara Monesmith, Irina Tcherepanova, Lois Dinterman

Patent number: 8153426Abstract: The invention relates to a method for the preparation of efficient antigen-presenting human ?? T cells, to the ?? T cells prepared by such a method, and to their use in immunotherapy, vaccination, vaccine development and diagnostics. Similar to dendritic cells (DCs) in potency and efficacy, these human ?? T cells process antigens and present antigenic peptides to ?? T cells and induce antigen-specific responses (proliferation and differentiation) in naïve ?? T cells. ?? T cells are easily purified from peripheral blood, acquire “maturation” status (expression of essential adhesion, co-stimulatory and major histocompatibility complex molecules) within 1 day of in vitro culture under stimulation and induce strong primary and secondary T helper cell and cytotoxic T cell responses. The ?? T cells may be used in a method of treatment of tumors or chronic or recurrent infectious diseases, in identification of novel tumor or pathogen-derived antigens, and in the diagnosis of the immune competence of a patient.Type: GrantFiled: August 11, 2005Date of Patent: April 10, 2012Assignee: University College Cardiff Consultants LimitedInventors: Bernhard Moser, Marlene Brandes Kuchen

Patent number: 8148094Abstract: The invention provides methods and compositions for simultaneously detecting the activation state of a plurality of proteins in single cells using flow cytometry. The invention further provides methods and compositions of screening for bioactive agents capable of coordinately modulating the activity of a plurality of proteins in single cells. The methods and compositions can be used to determine the protein activation profile of a cell for predicting or diagnosing a disease state, and for monitoring treatment of a disease state.Type: GrantFiled: February 17, 2009Date of Patent: April 3, 2012Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Garry P. Nolan, Omar D. Perez
