In the CNS, Y-27632 is known to regulate sleep and wakefulness, learning and memory, feeding, and energy. Here, we address its actions in relation to CNS disorders, and emphasize potential clinical applications of histamine receptor ligands (Table 1). In addition, as the effect of histamine on neur

When analyzing HIV/AIDS patients in São Paulo, we detected an association between HIV/HTLV-1/2 infection in black/pardo-colored individuals (OR 2.21, 95% CI 1.21–4.03). However, the majority of serum samples were from patients attending specialized services for hepatitis, other than HIV/AIDS or HTLV

Many studies have reported on the association between GST gene polymorphisms and pulmonary disorders but with controversial results [7]. In the present study, on comparing results of GSTP1 gene polymorphism among the studied COPD patient groups, it was found that heterozygote mutation was significa

It may seem counterintuitive that a lymphocyte which is unable to proliferate could have neoplastic potential since the very definition of neoplasia is one of autonomous clonal expansion of a cell. The lack of co-stimulatory molecules CD27 and CD28 can potentially be overcome by activating NK cell r

FFAR1 is highly expressed not only in β cells but also in α 76 7 (Segerstolpe et al., 2016), which gives the interesting perspective that 20-HETE may function both as an autocrine and as a paracrine regulator of islet cell function (Figure 1A), i.e., acting in symphony with the many other intra-isl

The structure and activity of GLUT1 has been most intensively studied in erythrocytes, in which this transporter makes up 10–20% of membrane protein content. Carruthers has shown that, while GLUT1 can exist and transport glucose as monomers, dimers and tetramers, in erythrocytes GLUT1 exists predomi

LbGlcK and the HsHxKIV-d-glucose complex (PDB entry 3IDH) [17] were superimposed from individual subunits. The active site regions revealed the key mm stock binding residues to be present for LbGlcK; also, the superposition showed that HsHxKIV had residues that were absent in LbGlcK, such as K169 a

Numerical models of blood regulation provide insight into the interaction of the cellular-level and macro-scale phenomena studied in silico, a term referring to computer simulations of the dynamics of complex biological systems as opposed to in vivo or in vitro experimental studies. These in silico

Introduction Conversion of visual input into electrical information and routing this information to the brain is the main function of the eye (Levin et al., 2011). These processes require a microenvironment that offers adequate supply with oxygen and nutrients and also removal of all unwanted and

One of the main mechanisms enabling recycling of intracellular redox-active iron is lysosomal degradation of ferritin in the process of autophagy, often referred to as ‘ferritinophagy’ [128]. Autophagy was suggested to contribute to ferroptotic cell death by promoting the degradation of iron storage

While more-detailed molecular studies on the mechanistic basis for heightened H3 receptor function in PAE rats are underway, we have also been exploring whether PAE alters other markers of histaminergic neurotransmission in affected brain regions. One question is whether PAE affected the number of h

Materials and methods Results and discussion We recently found that the GlyT1 N-terminal and C-terminal sequences could be modified by phophorylation, or partially lost under pathological conditions by calcium-dependent proteolysis (Baliova and Jursky, 2005, Baliova and Jursky, 2010). While re

Due to its unusually long pre-implantation period [20,21], the horse conceptus is entirely dependent on histotrophic nutrition for the first 40 days of gestation [22]. During the pre-implantation period, glucose transporters in the endometrium and conceptus membranes must deliver the glucose require
