The ectodomain of Toll-like receptor 9 is cleaved to generate a functional receptor. [PDF]

open access: yes, 2008
Mammalian Toll-like receptors (TLRs) 3, 7, 8 and 9 initiate immune responses to infection by recognizing microbial nucleic acids; however, these responses come at the cost of potential autoimmunity owing to inappropriate recognition of self nucleic acids.

Regulation of cytochrome P450 mRNA expression in primary porcine hepatocytes by selected secondary plant metabolites from chicory (Cichorium intybus L.) [PDF]

open access: yes, 2013
Chicory (Cichorium intybus) has been shown to induce enzymes of pharmacokinetic relevance (cytochrome P450; CYP). The aim of this study was to investigate the effects of selected secondary plant metabolites with a global extract of chicory root, on the ...

Cardiac Sigma Receptors – An Update

open access: yesPhysiological Research, 2018
More than four decades passed since sigma receptors were first mentioned. Since then, existence of at least two receptor subtypes and their tissue distributions have been proposed. Nowadays, it is clear, that sigma receptors are unique ubiquitous proteins with pluripotent function, which can interact with so many different classes of proteins.

Pregnancy reduces brain sigma receptor function [PDF]

open access: yesBritish Journal of Pharmacology, 1999
Sigma (σ) receptors have recently been cloned, though their endogenous ligand(s) remain unidentified. However, some neuroactive steroids, such as progesterone, have a high affinity for these receptors. Some σ ligands, such as DTG, (+)‐pentazocine and DHEA, act as σ ‘agonists’ by potentiating the neuronal response to NMDA. Others, such as haloperidol,

Crucial Interactions Between Selective Serotonin Uptake Inhibitors and Sigma-1 Receptor in Heart Failure

open access: yesJournal of Pharmacological Sciences, 2013
Depression is associated with a substantial increase in the risk of developing heart failure and is independently associated with increased cardiovascular morbidity and mortality. Inversely, cardiovascular disease can lead to severe depression.

Sigma-1 Receptors in Depression: Mechanism and Therapeutic Development

open access: yesFrontiers in Pharmacology, 2022
Depression is the most common type of neuropsychiatric illness and has increasingly become a major cause of disability. Unfortunately, the recent global pandemic of COVID-19 has dramatically increased the incidence of depression and has significantly ...

Hsp70 and Hsp40 inhibit an inter-domain interaction necessary for transcriptional activity in the androgen receptor. [PDF]

open access: yes, 2019
Molecular chaperones such as Hsp40 and Hsp70 hold the androgen receptor (AR) in an inactive conformation. They are released in the presence of androgens, enabling transactivation and causing the receptor to become aggregation-prone.

Pridopidine protects neurons from mutant-huntingtin toxicity via the sigma-1 receptor

open access: yesNeurobiology of Disease, 2019
Huntington's disease (HD) is a neurodegenerative disease caused by a CAG repeat expansion in the Huntingtin gene (HTT), translated into a Huntingtin protein with a polyglutamine expansion.

Potentiation of nerve growth factor-induced neurite outgrowth by fluvoxamine: role of sigma-1 receptors, IP3 receptors and cellular signaling pathways.

open access: yesPLoS ONE, 2008
BackgroundSelective serotonin reuptake inhibitors (SSRIs) have been widely used and are a major therapeutic advance in psychopharmacology. However, their pharmacology is quite heterogeneous.
