摘要:
A method and conjugate for selectively killing antigen-activated T cells are disclosed. The conjugate is composed of a substantially uncharged antisense compound targeted against the human cFLIP protein, and a reverse TAT (rTAT) polypeptide coupled covalently to the antisense compound. The rTAT polypeptide is effective to produce selective uptake of the conjugate into antigen-activated T cells, relative to the uptake of the conjugate into non-activated T cells. The cFLIP antisense compound causes activation induced cell death (AICD) of activated lymphocytes. The method is useful in treating transplantation rejection and autoimmune conditions.

摘要:
Provided are methods and compositions, including topical compositions, for inducing tolerance to a sensitizing agent known to provoke contact hypersensitivity in a subject. Included are methods of topically applying to the subject an effective amount of an antisense composition targeting the start site or splice site of a CFLAR mRNA.
摘要:
A method and composition for inducing human dendritic cells to a condition of reduced capacity for antigen-specific activation of T cells, and, in mature dendritic cells, increased production of extracellular IL-10 is disclosed. A population of dendritic cells is exposed to a substantially uncharged antisense compound, including partially positively charged, containing 12-40 subunits and a base sequence effective to hybridize to a target region within the sequence identified by SEQ ID NO:9, to form a duplex structure between the compound and transcript having a Tm of at least 45° C. Formation of the duplex blocks expression of full-length CD86 in the cells, which in turn leads to reduced capacity for antigen-specific activation of T cells, and, in mature dendritic cells, increased production of extracellular IL-10.

摘要:
A method and conjugate for selectively targeting activated hematopoietic cells, e.g., macrophage or T-lymphocyte cells, are disclosed. The conjugate is composed of a substantially uncharged antisense compound targeted against HIV, and a reverse TAT (rTAT) polypeptide coupled covalently to the antisense compound. The rTAT polypeptide is effective to produce selective uptake of the conjugate into activated, HIV-infected cells, e.g., activated, HIV-infected macrophage and T-lymphocyte cells. An exemplary embodiment of the invention provides an antisense compound directed to the HIV Vif gene, causing the production of defective HIV virions in an infected individual.
