  • Patent number: 8734854
    Abstract: A sub-atmospheric, negative pressure is applied to a growth factor starting material, such as whole blood, to release growth factors and plasma in a non-destructive medium. The released growth factors having a weight of about 70-76 kDaltons are applied in either a filtered or unfiltered state to a wound to promote healing of the wound. The released growth factors are applied topically to the area of a surface wound to effect healing. The released growth factors are also injected into soft tissue, such as a torn tendon, to promote tissue growth and healing. The growth factors are released in one method from a patient's own blood. In another method the growth factors are released from a whole blood source and freeze dried by conventional lyophilization. Then at a later date, the freeze dried product is reconstituted by normal saline for treatment of a patient's wound or for use in a surgical procedure.

  • Publication number: 20090104221
    Abstract: The present invention comprises the use of follicular dendritic cells (FDCs) or FDC-like cells to generate FDC-dependent, but T cell-independent, B cell responses to T cell-dependent antigens, with antigen-specific and polyclonal antibody production in ˜48 h. In another embodiment, a germinal center (GC) lymphoid tissue equivalent (LTE) was used to generate antigen-specific IgM, followed by switching to IgG. The GC LTE model can be used in vaccine assessment. Dual forms of immunogen were used in the GC LTE and in vivo. Dual immunogens resulted in rapid, specific IgM responses and enhanced IgG responses. This vaccine design approach can be used, for example, to provide rapid IgM protection (˜24-48 h) and high-affinity IgG more quickly in people moving to areas with endemic disease, or in people with T cell insufficiencies, who can be immunized to rapidly generate protective IgM.

  • Publication number: 20090022739
    Abstract: Blocking the voltage-gated potassium channel Kv1.1 of T-cells causes the robust and exclusive production of TNF-?, and thus can be used for eradication of cancer, improved eradication of infectious organisms, increased permeability of blood vessels and the blood brain barriers to given molecules and cells, and improved neuronal features, regeneration function and development. Blocking the voltage-gated potassium channel Kv1.1 of T-cells causes the robust and exclusive production of TNF-?. Similarly, unblocking of a blocked Kv1.1 channel or opening of a Kv1.1 channel will prevent the T-cells from producing and secreting excess amounts of TNF-?, thus being useful in the treatment of conditions such as rheumatoid arthritis and for treating neurological diseases associated with defected functioning and/or pathological block of the Kv1.1 channel, among them PNH associated with Kv1 Abs; Encephalitis associated with Kv1 Abs; and Episodic-ataxia type 1 (EA-1), in all of which the T-cell blocked Kv1.

  • Patent number: 7364842
    Abstract: This invention relates to the discovery that the transcription factors Pbx1 and HMG I are involved in retrovirus, e.g., HIV, replication. Thus, the invention provides methods of identifying modulators of these proteins. Such modulators can be used as reagents in in vitro assays to modulate expression of retroviral sequences and may be used to inhibit HIV replication in vivo.

  • Patent number: 7220559
    Abstract: This invention provides: a heteromyeloma, other than B6B11, capable of producing a trioma when fused with a human lymphoid cell, wherein the trioma is capable of producing a monoclonal antibody-secreting tetroma when fused with a second, antibody-secreting human lymphoid cell; a trioma fusion partner which does not produce antibody, obtained by fusing a heteromyeloma which does not produce antibody with a human lymphoid cell; a monoclonal antibody-secreting tetroma, obtained by fusing a trioma which does not produce antibody with an antibody-secreting human lymphoid cell; a method of producing a monoclonal antibody that specifically recognizes an antigen associated with a condition; a method of identifying an antigen associated with a condition using the trioma fusion partner; a method of diagnosing a condition using the trioma fusion partner; a method for preventing a condition; and compositions and therapeutic compositions comprising monoclonal antibodies produced using the trioma fusion partner.
