The colorectal cancer (CRC) subtyping consortium has unified six independent molecular classification systems, based on gene expression data, into a single consensus system with four distinct groups, known as the consensus molecular subtypes (CMS); clinical implications are discussed in this review based on articles relevant to the CMS of CRC indexed in PubMed as well as the authors’ own ...
Enhanced host rejection of tumor cells is the primary goal of cancer immunotherapy and, in many murine tumor models, has been accom plished hy engineering cells to express B7 costimulatory molecules or creating an environment rich in certain cytokines. We examined the effect of tumor cell B7-1 expression and administered recombinant interleukin 12 (IL-12) on the syngeneic host response to rapid...

Melanins are associated with virulence in several important human pathogens, but little is known about the immune response to this ubiquitous biologic compound. We hypothesized that melanin produced by the fungus Cryptococcus neoformans was immunogenic. C. neoformans melanin was purified from melanized fungal cells and was used to immunize C57BL/6, BALB/c, and T cell-deficient (nude) BALB/c mic...
BACKGROUND Surgery and radiation are the mainstays of therapy for human gliomas that are the most common primary brain tumors. Most recently, cell culture and animal studies provided the first convincing evidence that radiation not only eliminates tumor cells, but also modulates the immune response and likely improves anti-tumor immunotherapy. METHODOLOGY/PRINCIPAL FINDINGS We present an in v...
CD4(+) T cells orchestrate immune responses against fungi, such as Aspergillus fumigatus, a major fungal pathogen in humans. The complexity of the fungal genome and lifestyle questions the existence of one or a few immune-dominant Ags and complicates systematic screening for immunogenic Ags useful for immunotherapy or diagnostics. In this study, we used a recently developed flow cytometric assa...
Despite their common ability to activate intracellular signaling through CD80/CD86 molecules, cytotoxic T lymphocyte antigen 4 (CTLA-4)-Ig and CD28-Ig bias the downstream response in opposite directions, the latter promoting immunity, and CTLA-4-Ig tolerance, in dendritic cells (DCs) with opposite but flexible programs of antigen presentation. Nevertheless, in the absence of suppressor of cytok...
The in vivo induction of a CTL response using Antennapedia homeodomain (AntpHD) fused to a poorly immunogenic CTL epitope requires that the Ag is given in presence of SDS, an unacceptable adjuvant for human use. In the present report, we developed a hybrid CTL epitope delivery system consisting of AntpHD peptide vector formulated in liposomes as an alternative approach to bypass the need for SD...
For more than 2 centuries active immunotherapy has been at the forefront of efforts to prevent infectious disease [Waldmann TA (2003) Nat Med 9:269-277]. However, the decreased ability of the immune system to mount a robust immune response to self-antigens has made it more difficult to generate therapeutic vaccines against cancer or chronic degenerative diseases. Recently, we showed that the si...
Neisseria gonorrhoeae is one of the most prevalent sexually transmitted diseases worldwide with more than 100 million new infections per year. A lack of intense research over the last decades and increasing resistances to the recommended antibiotics call for a better understanding of gonococcal infection, fast diagnostics and therapeutic measures against N. gonorrhoeae. Therefore, the aim of th...
