The effectiveness of an injected caprine serum fraction-immunomodulator (CSF-I2) as an immunostimulant in male and female F-line and commercial turkey poults infected with fowl cholera (Pasteurella multocida) was examined in separate trials. In the first 2 of 3 controlled trials, the effects of an i.m. injection of CSF-I2 given 24 h prior to a P. multocida challenge, administered by s.c. inject...

The pivotal role that glutamate plays in the functioning of the central nervous system is well established. Several glutamate receptors and glutamate transporters have been extensively described in the central nervous system where they, respectively mediate glutamate effects and regulates extracellular glutamate levels. Recent studies have shown that glutamate not only has a role as neurotransm...

Chlamydia trachomatis, the agent of bacterial sexually transmitted infections, can manifest itself as either acute cervicitis, pelvic inflammatory disease, or a chronic asymptomatic infection. Inflammation induced by C. trachomatis contributes greatly to the pathogenesis of disease. Here we evaluated the anti-inflammatory capacity of naringenin, a polyphenolic compound, to modulate inflammatory...

The novel immunomodulator FTY720 causes lymphocytes from peripheral blood to accumulate in lymphoid tissues. In vivo, FTY720 is phosphorylated to FTY720-P, which binds to the sphingosine 1-phosphate receptor S1P(1). So far, it has been unclear where FTY720-P is produced. We demonstrate that platelets efficiently convert FTY720 to FTY720-P and release it into the extracellular space. This releas...

Type 1 diabetes (T1D) is caused by a deficiency of insulin as a result of an autoimmune destruction of the pancreatic β-cells. A possibility to preserve remaining β-cells in children with newly diagnosed T1D is of great importance since sustained β-cell function is recognized to result in reduced end-organ complications. Glutamic acid decarboxylase 65 (GAD65) is one of the major antigens target...

ES-62 is an immunomodulatory phosphorylcholine (PC)-containing glycoprotein secreted by the rodent filarial nematode Acanthocheilonema viteae. Previously, the use of knockout mice has revealed the effects of ES-62 on macrophages and dendritic cells to be dependent on TLR4. However, it is possible that ES-62 may interact with additional proteins on the surfaces of target cells and hence that cel...

We investigated the mechanism of action, safety, and efficacy of the Site-Specific Immunomodulator (SSI) QBECO, a novel immunotherapy for Crohn's disease (CD). Using human monocytic THP-1 cells, we demonstrate that SSI QBECO (derived from the common colon bacteria E. coli) activates macrophages to an M1 phenotype (associated with enhanced capacity to eliminate bacteria and activate innate immun...

Tinospora cordifolia (Thunb.) Miers, Menispermaceae, is a dioecious creeper, commonly known as "Giloe" or "Guduchi" with significant medicinal importance in the traditional systems of medicine. It is designated as Rasayana drug in Ayurveda and recommended for a number of diseases and also as adaptogen and immunomodulator. The safety and efficacy of herbal medicines are closely correlated with t...

Secondary loss of response (LoR) often precludes further use of infliximab in children with Crohn's disease. Immunomodulators may reduce the incidence of LoR but their combination with infliximab presents safety concerns. We aimed to determine the long-term durability of infliximab response in paediatric Crohn's, effect of immunomodulators on LoR, and secondarily the effect of infliximab on gro...

BACKGROUND Hemophagocytic lymphohistiocytosis (HLH) is an uncommon, potentially fatal, hyperinflammatory syndrome that may rarely complicate the clinical course of Orientia tsutsugamushi disease (scrub typhus). METHODS Here we describe the clinicopathological features, laboratory parameters, management, and outcome of three adult patients (1 female, 2 males) with scrub typhus associated HLH f...
