toll-like receptor 4 (tlr4), considered one of  the most important tlr, recognizes lipopolysaccharide of  gram-negative bacteria. recognition  of  ligands by  tlrs  induces signaling pathways resulting in activation of transcriptional factors such as nf-κb which are involved in  the  expression of  inflammatory cytokines and  chemokines. to  prevent  an inappropriate immune response, a complex ...

the innate immune system recognizes the presence of bacterial products through the expression of a family of membrane receptors known as toll-like receptors (tlrs). polymorphisms in tlrs have been shown to be associated with increased susceptibility to diseases such as inflammatory bowel disease. the aim of this study was to determine whether there was a correlation between polymorphisms of tlr...

objective: it has been shown that silybum marianum or its extracts have hepatoprotective, antioxidant, anticancer, anti-inflammatory and anti-diabetic effects. nitric oxide (no) plays an important role in neurotransmission, neuroprotection, neurotoxicity and pathological pain, as a neurotransmitter or neuromodulator in the central nervous system. therefore, this experiment was performed in orde...

background and objective: familial hypercholesterolemia (fh) is an autosomal trait, which is caused by mutations in low density lipoprotein receptor (ldlr) gene. fh penetrance is about 100% and worldwide prevalence for heterozygous subjects is almost 1 in 500 and for homozygous 1 in 1,000,000. the patients are at risk of premature coronary heart disease (chd) due to defective ldlr and hence cho...

atherosclerosis has serious role in coronary arteries disease,so it is important to establish effective strategies for prevention or even treatment of atherosclerosis. adiponectin, as one of the most abundant adipokines, has insulin sensitivity, anti-inflammatory and anti-atherogenic properties. disturbed adiponectin actions through its receptor, (adipor1 and adipor2) may be involved in atheros...

we have shown that buspirone, a partial agonist of 5-hydroxytryptamine 1a (5-ht1a) receptors, improves motor dysfunctions induced by 6-hydroxydopamine (6-ohda) and haloperidol in rats. the present work extends these findings by investigating the role of 5-ht1a receptors on catalepsy-like immobilization in rats, a model of parkinson’s disease. catalepsy was induced by unilateral infusion of 6-oh...

Background: Breast cancer is the most common cancer in women, containing approximately one third of all illnesses in women. Assessment of molecular markers is valuable in predicting the outcome of disease and decision making for optimal treatment. The purpose of this study was to determine the relationship between estrogen and progesterone receptors with Her-2, Ki67, P53, and clinicopathologica...

Chemokine receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [438, 437, 32]) comprise a large subfamily of 7TM proteins that bind one or more chemokines, family small cytokines typically possessing chemotactic activity for leukocytes. Additional hematopoietic and non-hematopoietic roles have been identified many chemokines in areas embryonic development, immune cell pr...

Opioid analgesics are clinically used to relieve severe pain in acute postoperative and cancer pain, also the long term chronic pain. The analgesic action is mediated by μ-, δ-, κ-receptors, but currently, with few exceptions for k-agonists, μ-agonists only ones therapy. Previously synthesized compounds diazotricyclodecane cores (DTDs) have shown their effectiveness binding opioid receptors. Fo...

In 2019, the coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), has killed more than 6.6 millions of people around world as end 2022. The long-term impact COVID-19 is persisted, including its on male reproduction. SARS-CoV-2 enters into host cells using angiotensin-converting enzyme (ACE2) and transmembrane serine protease (TMP...
