One approach to enhancing the T cell response to tumors is vaccination with mimotopes, mimics of tumor epitopes. While mimotopes can stimulate proliferation of T cells that recognize tumor-associated antigens (TAAs), this expansion does not always correlate with control of tumor growth. We hypothesized that vaccination with mimotopes of optimal affinity in(More)
We previously showed that immunization with a combination of TLR and CD40 agonists (combined TLR/CD40 agonist immunization) resulted in an expansion of Ag-specific CD8 T cells exponentially greater than the expansion observed to immunization with either agonist alone. We now show that the mechanism behind this expansion of T cells is the regulated(More)
The generation of tumor-specific T cells is hampered by the presentation of poorly immunogenic tumor-specific epitopes by the tumor. Here, we demonstrate that, although CD8+ T cells specific for the self/tumor Ag tyrosinase-related protein 2 (TRP2) are readily detected in tumor-bearing hosts, vaccination of either tumor-bearing or naive mice with an epitope(More)
Immunologic tolerance to endogenous antigens reduces antitumor responses. Gp70 is an endogenous tumor-associated antigen (TAA) of the BALB/c-derived colon carcinoma CT26. We found that expression of gp70 mRNA is detectable in tissues of mice 8 months of age and older. We showed that expression of gp70 establishes immunologic tolerance and affects antitumor(More)
We have previously shown that Toll-like receptor (TLR) agonists cooperate with CD40 to generate CD8 T cell responses exponentially larger than the responses generated with traditional vaccine formulations. We have also shown that combined TLR agonist/anti-CD40 immunization uniquely induces the upregulation of CD70 on antigen bearing dendritic cells (DCs).(More)
Type I IFNs are important for direct control of viral infection and generation of adaptive immune responses. Recently, direct stimulation of CD4(+) T cells via type I IFNR has been shown to be necessary for the formation of functional CD4(+) T cell responses. In contrast, we find that CD4(+) T cells do not require intrinsic type I IFN signals in response to(More)
If Bacillus anthracis (BA), the organism that causes anthrax, is known or suspected to have contaminated a building, a critical decision is what level of contamination is unacceptable. This decision has two components: (1) what is the relationship between the degree of contamination and the risk to occupants, (2) and what is an acceptable risk to occupants?(More)
The California Energy Commission is considering updating its requirements for residential ventilation in the next round of its energy code, known as " Title 24. " This report contains recommendations for potential changes to the code. These recommendations must be further developed into specific wording before they can be formally considered.
