Editorial: Sigma Receptors [PDF]
Frontiers in Pharmacology, 2020 Sigma receptors were initially described as opioid receptors (Martin et al., 1976). They are now considered neither related to other types of receptor nor to each other. While several ligands used to study these receptors [e.g., di-O-tolyl guanidine (DTG) and haloperidol] have similar affinities for the sigma-1 and sigma-2 receptors, these proteins ...

Sigma receptors and neurological disorders [PDF]
Pharmacological Reports, 2021 AbstarctSigma receptors were identified relatively recently, and their presence has been confirmed in the central nervous system and peripheral organs. Changes in sigma receptor function or expression may be involved in neurological diseases, and thus sigma receptors represent a potential target for treating central nervous system disorders.

Sigma Receptor Binding Assays [PDF]
Current Protocols in Pharmacology, 2015 AbstractSigma receptors, both Sigma‐1(S1R) and Sigma‐2 (S2R), are small molecule‐regulated, primarily endoplasmic reticulum (ER) membrane‐associated sites. A number of drugs bind to sigma receptors, including the antipsychotic haloperidol and (+)‐pentazocine, an opioid analgesic.

The Sigma 2 receptor promotes and the Sigma 1 receptor inhibits mu-opioid receptor-mediated antinociception [PDF]
Molecular Brain, 2020 Abstract The Sigma-1 receptor (σ1R) has emerged as an interesting pharmacological target because it inhibits analgesia mediated by mu-opioid receptors (MOR), and also facilitates the development of neuropathic pain. Based on these findings, the recent cloning of the Sigma-2 receptor (σ2R) led us to investigate its potential role as a regulator ...

Pharmacological Research, 2023 Over the last decade, sigma-1 receptor (Sig1R) has been recognized as a valid target for the treatment of seizure disorders and seizure-related comorbidities. Clinical trials with Sig1R ligands are underway testing therapies for the treatment of drug-resistant seizures, developmental and epileptic encephalopathies, and photosensitive epilepsy. However,

The Sigma Enigma: A Narrative Review of Sigma Receptors
Cureus, 2023 The sigma-1 and sigma-2 receptors were first discovered in the 1960s and were thought to be a form of opioid receptors initially. Over time, more was gradually learned about these receptors, which are actually protein chaperones, and many of their unique or unusual properties can contribute to a range of important new therapeutic applications.

TMEM97 and PGRMC1 do not mediate sigma-2 ligand-induced cell death [PDF]
, 2019 Sigma-2 receptors have been implicated in both tumor proliferation and neurodegenerative diseases. Recently the sigma-2 receptor was identified as transmembrane protein 97 (TMEM97).

Sigma-1 Receptor Plays a Negative Modulation on N-type Calcium Channel
Frontiers in Pharmacology, 2017 The sigma-1 receptor is a 223 amino acids molecular chaperone with a single transmembrane domain. It is resident to eukaryotic mitochondrial-associated endoplasmic reticulum and plasma membranes.
