ICOS-ImmunoPET Monitors T Cell Activation After Combination Immune Checkpoint Blockade in a Mouse Model of Melanoma Brain Metastasis. [PDF]

Adv Sci (Weinh)
ICOS‐immunoPET noninvasively visualizes activated T cells in melanoma brain metastases following combined anti‐PD‐1/anti‐CTLA‐4 therapy. Clinical translation of this imaging approach may improve patient stratification and treatment monitoring and serve as a quantitative imaging endpoint to support immunotherapy development and clinical trials in brain ...

Increased Binding of [¹⁸F]Nifene, a PET Imaging Probe for α4β2* Nicotinic Acetylcholinergic Receptors in Hippocampus-Subiculum of Postmortem Human Parkinson's Disease Brain. [PDF]

Synapse
[18F]Nifene, a PET imaging probe for α4β2* nicotinic acetylcholine receptors, was used to discretely measure changes in hippocampus (HP) and subiculum (SUB) of postmortem Parkinson's disease (PD) cases compared to cognitively normal (CN) cases. Significant increased [18F]nifene binding in PD was observed.

Receptor localization of steroid hormones and drugs: discoveries through the use of thaw-mount and dry-mount autoradiography

Brazilian Journal of Medical and Biological Research, 1998
The history of receptor autoradiography, its development and applications, testify to the utility of this histochemical technique for localizing radiolabeled hormones and drugs at cellular and subcellular sites of action in intact tissues.

Modification of dopamine neurotransmission in the nucleus accumbens of rats deficient in n–3 polyunsaturated fatty acids

Journal of Lipid Research, 2000
We studied the effects of a diet chronically deficient in α-linolenic acid, the precursor of long-chain n–3 polyunsaturated fatty acids, on dopaminergic neurotransmission in the shell region of the nucleus accumbens of rats.

Differential Sphingosine-1-Phosphate Receptor-1 Protein Expression in the Dorsolateral Prefrontal Cortex Between Schizophrenia Type 1 and Type 2

Frontiers in Psychiatry, 2022
Understanding the etiology and treatment approaches in schizophrenia is challenged in part by the heterogeneity of this disorder. One encouraging progress is the growing evidence that there are subtypes of schizophrenia.

Actinide bioimaging in tissues: Comparison of emulsion and solid track autoradiography techniques with the iQID camera. [PDF]

PLoS ONE, 2017
This work presents a comparison of three autoradiography techniques for imaging biological samples contaminated with actinides: emulsion-based, plastic-based autoradiography and a quantitative digital technique, the iQID camera, based on the numerical ...

Asymmetric Synthesis of Spirocyclic 2-Benzopyrans for Positron Emission Tomography of σ1 Receptors in the Brain

Pharmaceuticals, 2014
Sharpless asymmetric dihydroxylation of styrene derivative 6 afforded chiral triols (R)-7 and (S)-7, which were cyclized with tosyl chloride in the presence of Bu2SnO to provide 2-benzopyrans (R)-4 and (S)-4 with high regioselectivity.

In Vitro and In Vivo Characterization of Dibenzothiophene Derivatives [¹²⁵I]Iodo-ASEM and [¹⁸F]ASEM as Radiotracers of Homo- and Heteromeric α7 Nicotinic Acetylcholine Receptors

Molecules, 2020
The α7 nicotinic acetylcholine receptor (α7 nAChR) is involved in several cognitive and physiologic processes; its expression levels and patterns change in neurologic and psychiatric diseases, such as schizophrenia and Alzheimer’s disease,
