iAPA-based dendritic cells/cytotoxic T lymphocytes: A cell-based product composed of dendritic cells (DCs) pulsed with tumor-associated antigens (TAAs) and devoid of the inhibitory effect of antigen presentation attenuators (iAPA) combined with cytotoxic T-lymphocytes (CTLs) (iAPA-DC/CTL), with potential immunostimulating and antineoplastic activities. DCs are transduced with a viral vector containing small interfering RNAs (siRNAs) against APAs, which prevents the expression of APA genes and inhibits attenuation of antigen presentation. Upon administration of iAPA-DC/CTL, the DCs are able to efficiently present antigens to the immune system, stimulate the immune system against tumor-associated antigens (TAAs) and hyperactivate TAA-specific CTLs and T-helper cells. Also, the iAPA-based DCs inhibit the activity of the T-regulatory cells (Tregs), thereby abrogating their negative effect on CTL activation and preventing their immunosuppressive activity against TAAs. Altogether, this inhibits tumor cell proliferation. Additionally, the administered CTLs induce direct cancer cell lysis. APAs negatively regulate antigen presentation, activate Tregs and their immunosuppressive activity, affect inflammatory cytokine production by DCs, and negatively regulate the immunostimulatory activity of DCs; they have an overall inhibitory effect on the stimulation of the immune system.

iobitridol: A water-soluble, tri-iodinated, non-ionic monomeric benzoate derivative and contrast medium used in diagnostic radiography. Upon administration, iobitridol is distributed through the vascular system and interstitial space. Like other organic iodine compounds, this agent blocks x-rays and appears opaque on x-ray film thus, enhancing the visibility of body parts containing this agent. Iobitridol is rapidly removed by the kidneys in an unchanged form, and in cases of renal failure, heterotropic excretion occurs via the biliary route.
iodinated contrast dye: A contrast agent containing an iodine-based dye used in many diagnostic imaging examinations, including computed tomography, angiography, and myelography. Check for active clinical trials using this agent. (NCI Thesaurus)
iodinated polyethylene glycol-based hydrogel tissue marker: A radiopaque hydrogel containing cross-linked, iodinated polyethylene glycol (PEG) particles in a viscous carrier, with potential use as a contrast agent to enhance marking of soft tissue during a surgical procedure and concomitant radiotherapy upon computed tomography (CT), magnetic resonance (MR) and ultrasound imaging. Upon intratumoral injection, iodinated PEG-based hydrogel tissue marker localizes to and is maintained in soft tissue. Upon MR, ultrasound and/or CT imaging, the visualization of the tumor tissue is enhanced, which can facilitate tumor removal and image-guided radiotherapeutic treatment. The hydrogel particles are stable and visible through 3 months, after which they liquefy, and are absorbed by the body and cleared in the urine. Check for active clinical trials using this agent.

iodine I 123: A radioactive isotope of iodine, a nonmetallic element of the halogen group with an atomic mass of 123 and a half-life of 13.2 hours with radioisotopic activity. Selectively accumulating in the thyroid tissue, iodine I 123 emits gamma rays that can be detected with gamma scintigraphy, allowing localization of thyroid tissue. This agent may be used as a tracer in whole body scintigraphy (WBS) to localize thyroid carcinoma metastases. Check for active clinical trials using this agent. (NCI Thesaurus)
iodine I 123 ADAM: A radiopharmaceutical containing the serotonin transporter (SERT) ligand ADAM [2-((2-((dimethylamino)methyl)phenyl)thio)-5-iodophenylamine] labeled with the radioisotope iodine I 123, with SERT-binding and radioisotope activities. Upon administration, iodine I 123 ADAM selectively binds to SERT-expressing cells; subsequently, SERT-expressing tissues may be visualized using single photon emission computed tomography (SPECT). SERT is a monamine transporter protein found in the membranes of neurons and platelets; in neurons it transports the neurotransmitter serotonin from synaptic spaces into presynaptic neurons, terminating serotonin's function.

iodine I 123 anti-CEA recombinant diabody T84.66: A radioimmunoconjugate comprised of a recombinant scFv dimer diabody of a monoclonal antibody against human carcinoembryonic antigen (CEA) labeled with iodine I 123 (I-123) with potential radioimmunolocalization applications. The antibody moiety of iodine I 123 anti-CEA recombinant diabody T84.66 binds to cells expressing CEA, selectively delivering I-123 upon cellular internalization and allowing the scintigraphic imaging of CEA-expressing tumor cells. CEA, a tumor associated antigen, is overexpressed in many cancer types, including gastrointestinal, breast, non-small cell lung, and thyroid cancers. Compared to whole monoclonal antibodies, diabody fragments offer the advantages of rapid tumor targeting, rapid blood clearance, more uniform tumor distribution, and a lower potential for eliciting an immune response.
