'The mechanisms of CD4(+) T-cell count decline, the hallmark of HIV disease progression, and its relationship to elevated levels of immune activation are not fully understood. Massive depletion of CD4(+) T cells occurs during the course of HIV-1 infection, so that maintenance of adequate CD4(+) T-cell levels probably depends primarily ... More
Antibodies to self-antigens predispose to primary lung allograft dysfunction and chronic rejection.

Primary graft dysfunction (PGD) is a known risk factor for bronchiolitis obliterans syndrome (BOS) after lung transplantation. Here, we report that preformed antibodies to self-antigens increase PGD risk and promote BOS. ... More
Serum biomarker profiles and response to neoadjuvant chemotherapy for locally advanced breast cancer.

PubMed ID18474099
Neoadjuvant chemotherapy has become the standard of care for the diverse population of women diagnosed with locally advanced breast cancer. Serum biomarker levels are increasingly being investigated for their ability to predict therapy response and aid in the development of individualized treatment regimens. Multianalyte profiles may offer greater predictive power ... More
Inflammation driven by tumour-specific Th1 cells protects against B-cell cancer.
The immune system can both promote and suppress cancer. Chronic inflammation and proinflammatory cytokines such as interleukin (IL)-1 and IL-6 are considered to be tumour promoting. In contrast, the exact nature of protective antitumour immunity remains obscure. Here, we quantify locally secreted cytokines during primary immune responses against myeloma and ... More
In vitro toxicity assessment of amphiphillic polymer-coated CdSe/ZnS quantum dots in two human liver cell models.

Semiconductor quantum dots (Qdots) are a promising new technology with benefits in the areas of medical diagnostics and therapeutics. Qdots generally consist of a semiconductor core, capping shell, and surface coating. The semiconductor core of Qdots is often composed of group II and VI metals (e.g., Cd, Se, Te, Hg) ... More
Gene expression in HIV-1/Mycobacterium tuberculosis co-infected macrophages is dominated by M. tuberculosis.
The resurgence of tuberculosis worldwide has closely mirrored the HIV pandemic. In regions like sub-Saharan Africa, a large proportion of individuals are co-infected with Mycobacterium tuberculosis and HIV. Macrophages are the reservoir host cells for both pathogens, however the interactions between both pathogens in co-infected cells remain poorly understood. Thus, ... More
Campylobacter jejuni-mediated induction of CC and CXC chemokines and chemokine receptors in human dendritic cells.

PubMed ID22689814
Campylobacter jejuni is a leading worldwide bacterial cause of human diarrheal disease. Although the specific molecular mechanisms of C. jejuni pathogenesis have not been characterized in detail, host inflammatory responses are thought to be major contributing factors to the resulting typical acute colitis. The intestinal mucosal chemokine response is particularly ... More

There is a growing interest in the role that cancer biomarkers, metastasis-related molecules, and chemokines may play in the development and progression of various cancers. However, few studies have addressed the reliability of such biomarkers in healthy individuals over time. The objective of this study was to investigate the temporal ... More
