We sought to identify cells and cytokines in bronchoalveolar lavage (BAL) fluids that distinguish asthma from healthy control subjects and those that distinguish controlled asthma from uncontrolled asthma. Following informed consent, 36 human subjects were recruited for this study. These included 11 healthy control subjects, 15 subjects with controlled asthma with FEV1≥80% predicted and 10 subj...
Phytocannabinoids that do not produce psychotropic effects are considered of special interest as novel therapeutic agents in CNS diseases. A cannabigerol quinone, the compound VCE-003, has been shown to alleviate symptoms in a viral model of multiple sclerosis (MS). Hence, we studied T cells and macrophages as targets for VCE-003 and its efficacy in an autoimmune model of MS. Proliferation, cel...
Chronic infection with Toxoplasma gondii induces a potent resistance against reinfection, and IFN-γ production by CD8(+) T cells is crucial for the protective immunity. However, the molecular mechanisms that regulate the secondary response remain to be elucidated. In the current study, we examined the role of IL-2 in IFN-γ production by CD8(+) immune T cells in their secondary responses using T...
Multiple sclerosis (MS) is a typical CD4 T cell-mediated autoimmune disease of the central nervous system (CNS) that leads to inflammation, demyelination, axonal damage, glial scarring and a broad range of neurological deficits. While disease-modifying drugs with a good safety profile and moderate efficacy have been available for 20 years now, a growing number of substances with superior therap...
Anaplastic lymphoma kinase (ALK), physiologically expressed only by nervous system cells, displays a remarkable capacity to transform CD4(+) T lymphocytes and other types of nonneural cells. In this study, we report that activity of nucleophosmin (NPM)/ALK chimeric protein, the dominant form of ALK expressed in T cell lymphomas (TCLs), closely resembles cell activation induced by IL-2, the key ...
The canonical Wnt/β-catenin signaling pathway plays an important role in thymocyte development and T cell migration, but little is known about its role in naive-to-effector differentiation in human peripheral T cells. We show that activation of Wnt/β-catenin signaling arrests human peripheral blood and cord blood T lymphocytes in the naive stage and blocks their transition into functional T eff...
Immune and endocrine responses play a critical role in allowing animals to adjust to environmental perturbations. We measured immune and endocrine related markers in multiple samples from individuals from two managed-care care dolphin groups (n = 82 samples from 17 dolphins and single samples collected from two wild dolphin populations: Indian River Lagoon, (IRL) FL (n = 26); and Charleston, (C...
We and others have shown that regulatory T cells (Treg) accumulate dramatically with age in both humans and mice. Such Treg accrual contributes to age-related immunosenescence as they reduce the response to tumors and parasite infection. While we reported earlier that aged Treg have decreased expression of the pro-apoptotic molecule Bim and germline deletion of Bim promoted earlier accumulation...
Cysticidal treatment of neurocysticercosis, an infection of humans and pig brains with Taenia solium, results in an early inflammatory response directed to cysts causing seizures and focal neurological manifestations. Treatment-induced pericystic inflammation and its association with blood brain barrier (BBB) dysfunction, as determined by Evans blue (EB) extravasation, was studied in infected u...
Molecular events that drive disc damage and low back pain (LBP) may precede clinical manifestation of disease onset and can cause detrimental long-term effects such as disability. Biomarkers serve as objective molecular indicators of pathological processes. The goal of this study is to identify systemic biochemical factors as predictors of response to treatment of LBP with epidural steroid inje...
