Enzymatic debridement is a therapeutic strategy used clinically to remove necrotic tissue from wounds. Some of the enzymes utilized for debridement have been tested against bacterial pathogens, but the effectiveness of these agents in dispersing clinically relevant biofilms has not been fully characterized. Here, we developed an in vitro Staphylococcus aureus biofilm model that mimics wound-lik...
Intraperitoneal chemotherapy together with cytoreductive surgery is the standard of care for a number of peritoneal surface malignancies. However, this approach fails to maintain the complete response and disease recurs due to microscopic residual disease. Although safer than systemic chemotherapy regimens, locoregional treatment with chemotherapeutics can induce toxicity which is a major conce...
We have evaluated the capacity of dendritic cells to function as antigen-presenting cells (APCs) for influenza and have examined their mechanism of action. Virus-pulsed dendritic cells were 100 times more efficient than bulk spleen cells in stimulating cytotoxic T lymphocyte (CTL) formation. The induction of CTLs required neither exogenous lymphokines nor APCs in the responding T cell populatio...
Murine B-1 cells are thought to develop from Ig- progenitors early in ontogeny and to expand by self-renewal. To examine the early development of Ig+ precursors of B-1 cells for bromelain-treated mouse RBC, the transient presence of RidA, a rat anti-Id mAb for V(H)11/Vkappa9-type anti-bromelain-treated mouse Abs, was produced in neonatal mice. The presence of RidA during days 0 to 10 of age res...
Background Bromelain is a collective name for proteolytic enzymes or proteases (natural proteolytic enzymatic complex) found in tissues including stems, fruit and leaves of the pineapple (Ananas comosus var. comosus) and of other plant species of the family Bromeliaceae [1]. Is a bioactive agent possessing remarkable therapeutic properties such as reversible inhibition of platelet aggregation, ...
Bromelain (Br) is a cysteine peptidase (GenBank AEH26024.1) from pineapple, with over 40 years of clinical use. The constituents mediating its anti-inflammatory activity are not thoroughly characterized and no peptide biomarker exists. Our objective is to characterize Br raw material and identify peptides in the plasma of Br treated mice. After SDS-PAGE in-gel digestion, Br (VN#3507; Middletown...
NADPH-cytochrome c reductase in rat liver microsomes was solubilized by bromelain digestion and purified to homogeneity. An antibody preparation obtained by immunization with this enzyme was found to inhibit the NADPHcytochrome c reductase activity of both the purified enzyme and intact microsomes by more than 90%. This antibody also inhibited the NADPH-dependent peroxidation of microsomal lipi...
BACKGROUND The botanical relation between grass and cereal grains may be relevant when diagnosing food allergy to cereals. The aim was to investigate the diagnostic specificity of skin prick test (SPT) and specific immunoglobulin E (sIgE) tests to cereals and peanut in grass pollen allergic subjects without history of, and clinically reactions to foods botanically related to grass. METHODS 70...
