Most therapies for autoimmune and inflammatory diseases either neutralize or suppress production of inflammatory cytokines produced by activated macrophages (e.g., TNFα, IL-1, IL-6, IL-17, GM-CSF). However, no approved therapies directly target this activated subset of macrophages. First, we undertook to examine whether the folate receptor beta (FR-β) positive subpopulation of macrophages, which marks the inflammatory subset in animal models of rheumatoid arthritis, might constitute the prominent population of macrophages in inflamed lesions in humans. Next, we utilized anti-FR-β monoclonal antibodies capable of mediating antibody-dependent cell cytotoxicity (ADCC) to treat animal models of rheumatoid arthritis and peritonitis. Human tissue samples of rheumatoid arthritis, Crohns disease, ulcerative colitis, idiopathic pulmonary fibrosis, nonspecific interstitial pneumonia, chronic obstructive pulmonary disease, systemic lupus erythematosus, psoriasis, and scleroderma are all characterized by

The folate receptor (FR) is a cell over expressed on the surface of certain cancers, this occurs most frequently in ovarian cancers. Some normal tissues

The folate receptor α (FRα)-targeting antibody-drug conjugate (ADC), IMGN853, shows great antitumor activity against FRα-expressing tumors in vivo, but patient selection and consequently therapy outcome are based on immunohistochemistry. The aim of this study is to develop an antibody-derived immuno-PET imaging agent strategy for targeting FRα in ovarian cancer as a predictor of treatment success. We developed [89Zr]Zr-DFO-M9346A, a humanized antibody-based radiotracer targeting tumor-associated FRα in the preclinical setting. [89Zr]Zr-DFO-M9346As binding ability was tested in an in vitro uptake assay using cell lines with varying FRα expression levels. The diagnostic potential of [89Zr]Zr-M9346A was evaluated in KB and OV90 subcutaneous xenografts. Following intravenous injection of [89Zr]Zr-DFO-M9346A (~90 μCi, 50 μg), PET imaging and biodistribution studies were performed. We determined the blood half-life of [89Zr]Zr-DFO-M9346A and compared it to the therapeutic, radioiodinated ADC [131I]

TapImmune Inc. (OTCQB:TPIV) is pleased to announce that a new grant funded Phase I clinical study on the safety and Immunogenicity of folate receptor alpha peptide vaccine in patients with advanced stage epithelial ovarian cancer has started at the Mayo Clinic, Rochester, MN. The folate receptor alpha peptides being used in this study are the same ones that are being used in a current Phase I study in breast and ovarian cancer. Folate receptor alpha is over a 100 fold elevated in 90% of ovarian cancer cells and is thus an excellent target for immunotherapy.. In this new trial the folate alpha receptor peptides are loaded on to the patients own dendritic cells. Dendritic cells (DCs) are often called natures adjuvants and thus have become an essential target in efforts to generate therapeutic immunity against cancer. Dendritic cell vaccination aims to induce tumour-specific effector T cells (eg, IL 17 secreting T Cells) that can reduce tumor mass specifically and induce immunological memory to ...

The α human folate receptor (αhFR), or KB cell folate receptor, gene contains two major promoters that produce transcripts, KB1 and KB4, varying only in the length and sequence of their 5′ untranslated regions (UTRs). Using RNase protection assays specific for each isoform, we show that the level of expression of these two transcripts is tissue-specific, indicating that promoter usage is regulated, not constitutive. RNA stabilities and translational efficiencies of the KB1 and KB4 transcripts were compared to determine the functional significance of the different 5′ UTRs. Analyses of RNA turnover in vivo with actinomycin D to block new transcription and in vitro with a cytoplasmic extract indicate no discernible differences in the stabilities of the two transcripts. However, the KB4 transcript is 2-3-fold more efficiently translated in wheat germ extracts in vitro and transfected CHO cells in vivo. Also, high ionic strength, which favours the formation of RNA secondary structure, ...

In these current studies in the SHR model, we investigated whether risk for features of the metabolic syndrome might be influenced by genetically determined variation in folate and sulfur amino acid metabolism. We found that genetically determined reductions in expression levels of Folr1 may be contributing to decreased renal tubular reabsorption of folate, reduced plasma folate levels, increased plasma levels of cysteine, and consequent disturbances in lipid and glucose metabolism. We implicate a functional role for a promoter variant in Folr1 in these processes based on a combination of genetic and metabolic studies in RI, transgenic, and congenic strains together with promoter function studies in HEK293 cells.. Mechanisms that may connect folate deficiency with disturbances of lipid and glucose metabolism are not fully understood. One possibility is that reduced availability of folate for homocysteine remethylation might result in deficiency of S-adenosylmethionine and accumulation of ...

During human pregnancy, the specialized epithelial cells of the placenta (cytotrophoblasts) come into direct contact with immune cells in several locations. In the fetal compartment of the placenta, cytotrophoblast stem cells lie adjacent to macrophages (Hofbauer cells) that reside within the chorionic villus stroma. At sites of placental attachment to the mother, invasive cytotrophoblasts encounter specialized maternal natural killer (NK) cells (CD56bright), macrophages, and T cells that accumulate within the uterine wall during pregnancy. Here we tested the hypothesis that fetal cytotrophoblasts can direct the migration of these maternal immune cells. First, we assayed the chemotactic activity of cytotrophoblast conditioned medium samples, using human peripheral blood mononuclear cells as targets. The placental samples preferentially attracted NK cells (both CD56dim and CD56bright), monocytes, and T cells, suggesting that our hypothesis was correct. A screen to identify chemokine activity ...

SYMPTOMS OF PULMONARY TUBERCULOSIS. As showing the numerous pitfalls in the way of accurate clinical diagnosis of pulmonary tuberculosis, L. Hofbauer records his frequent observation in military patients who had sustained gunshot wounds of the jaws, of a tendency to haemoptysis persisting even after the wounds had healed. This was accompanied revealed showers of moist rales at the apices (where there was usually pronounced dullness), as also about the hilum. As these patients were losing weight the clinical picture pointed to tuberculosis. Nevertheless, prolonged observation, and repeated tests and bacteriological examinations afforded no confirmation of it, and in the result all the men made complete recoveries. Hofbauer can only attribute the anomalous symptoms to a defective aeration of the lungs from shallow breathing due to the injury.

A blog post discussing preliminary research hinting that for some with schizophrenia, the presence of folate receptor autoantibodies might perturb folate levels and use of folinic acid may positively affect symptoms

Folate receptor alpha (FOLR1/FRA) is reported to be overexpressed in epithelial ovarian cancers (EOC), especially the serous histotype. Further, while dysregulation of the folate-dependent 1-carbon cycle has been implicated in tumorogenesis, little is known relative to the potential mechanism of action of FOLR1 expression in these processes. We therefore investigated the expression of FOLR1, other folate receptors, and genes within the 1-carbon cycle in samples of EOC, normal ovary and fallopian tube on a custom TaqMan Low Density Array. Also included on this array were known markers of EOC such as MSLN, MUC16 and HE4. While few differences were observed in the expression profiles of genes in the 1-carbon cycle, genes previously considered to be overexpressed in EOC (e.g., FOLR1, MSLN, MUC16 and HE4) showed significantly increased expression when comparing EOC to normal ovary. However, when the comparator was changed to normal fallopian tube, these differences were abolished, supporting the hypothesis

NMI-500 is a folate targeted theranostic containing a taxane therapy designed to overcome multidrug resistance in cancer. Taxane-based chemotherapy is a primary and secondary line of treatment for ovarian cancers, however dose limiting toxicities and multidrug resistance limit their effectiveness.. To improve tumor pharmacodynamics, NMI-500 targets the folate receptor which is expressed on over 80% of ovarian cancers. NMI-500 is also an effective MRI contrast agent; annotated with a gadolinium chelate which allows MRI to be used to identify if NMI-500 is accumulating in tumors. Nemucore has successfully tracked the accumulation of NMI-500 and longitudinally tracked tumor growth using MRI. In preclinical models NMI-500 has shown significant uptake in folate receptor positive tumors with reduced off-target toxicity.. Multidrug resistant cancer cells require folate to grow, targeting the folate receptor to deliver a highly lethal payload gives us a novel way to kill these aggressive tumors. These ...

Folate, act as an one-carbon units donator or acceptor, participate in numerous biochemical reactions. Because mammals cant synthesize folic acid de novo, obtain from diet or from microbial breakdown in the gut is essential. Pathological study revealed that tumor cell expressing high level of folate receptors (FR) comparing to normal tissue. Therefore, exploring the application of folate-related physiological properties as an anticancer strategy arose worldwide interesting. Previous studies in lung cancer revealed a positive correlation in folate receptors overexpression and efficacy of antifolate chemotherapy. Here we describe prolong Alimta treatment would prompt lung cancer cells malignancy. Cultivation of lung cancer CL1-0, CL1-5, and A549 in low dose Alimta (15-30 ng/mL) for 2-3 weeks would dramatically cause cell morphology change .

We describe an integrated approach for detection of diagnostic markers using in situ assembled optical diffraction gratings in combination with immunomagnetic capture. Folate receptor (FR), a serum protein indicative of various cancers, was chosen as a model system to demonstrate the potential of the method. Magnetic beads coupled to FR antibody were used to capture FR from serum. The FR-bound magnetic beads self-assembled onto microcontact-printed folate-coupled BSA (F-BSA) patterns to form diffraction gratings which served to detect FR by measuring the diffraction intensities caused by laser illumination. The FR-containing beads, upon binding to the F-BSA surface, served as intrinsic signal enhancement agents, circumventing the need for additional enzymatic signal amplification or fluorescent labeling steps. With this approach, a detection sensitivity of 700 fM (20 pg/mL) was achieved. The potential use of this approach in clinical diagnostics was demonstrated by measuring FR concentration in blood

This gene encodes a transmembrane proton-coupled folate transporter protein that facilitates the movement of folate and antifolate substrates across cell membranes, optimally in acidic pH environments. This protein is also expressed in the brain and choroid plexus where it transports folates into the central nervous system. This protein further functions as a heme transporter in duodenal enterocytes, and potentially in other tissues like liver and kidney. Its localization to the apical membrane or cytoplasm of intestinal cells is modulated by dietary iron levels. Mutations in this gene are associated with autosomal recessive hereditary folate malabsorption disease. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2013 ...
