AMPA Receptor Auxiliary Proteins of the CKAMP Family

2019

α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are assembled of four core subunits and several additional interacting proteins. Cystine-knot AMPA receptor-modulating proteins (CKAMPs) constitute a family of four proteins that influence the trafficking, subcellular localization and function of AMPA receptors. The four CKAMP family members CKAMP39/shisa8, CKAMP44/shisa9, CKAMP52/shisa6 and CKAMP59/shisa7 differ in their expression profile and their modulatory influence on AMPA receptor function. In this review, I report about recent findings on the differential roles of CKAMP family members.

Immune tolerance disruption by human parvovirus B19 viral infection mechanisms

2013

Virusinfektioita pidetään kasvavissa määrin suurimpana ympäristöperäisenä syynä, joka vaikuttaa autoimmuunisairauksien kehitykseen ja autoimmuniteetin muodostukseen. Esimerkiksi parvovirus B19 (B19V) on yhdistetty punahukkaan sekä nivelreumaan. On todettu, että B19V:n ei-rakenteellinen proteiini 1 (NS1) aiheuttaa apoptoosia soluissa, jotka eivät tavallisesti ole B19V infektion kohteena. Lisäksi hiljattain on osoitettu, että apoptoosin seurauksena muodostuvat apoptoottiset kappaleet kykenevät esittelemään antigeenejä niitä esittelemään erikoistuneille soluille, kuten makrofageille tai dendriittisoluille. Tämän tutkimuksen tarkoituksena on löytää B19V infektioon liittyviä autoantigeenejä sekä…

Binding of RNA Aptamers to Membrane Lipid Rafts: Implications for Exosomal miRNAs Transfer from Cancer to Immune Cells

2020

Intraluminal vesicles (ILVs) are released into the extracellular space as exosomes after the fusion of multivesicular bodies (MVBs) with the plasma membrane. miRNAs are delivered to the raft-like region of MVB by RNA-binding proteins (RBPs). RNA loading into exosomes can be either through direct interaction between RNA and the raft-like region of the MVB membrane, or through interaction between an RBP&ndash

Properties of tuberomammillary histamine neurones and their response to galanin.

1991

Histaminergic neurones in the tuberomammillary nucleus possess electrophysiological properties which distinguish them from other neurones in their neighborhood. Their resting potential is -50 mV and they are spontaneously active at about 2 Hz in a slice preparation. They display a transient outward rectification and an anomalous inward rectification. Bath application of galanin (0.1 microM) reduced their firing rate significantly and hyperpolarized them slightly.

Retained pieces of wood in the retromaxillary space: a case report.

1995

Detection and operative removal of wood as a foreign body in the cranio-maxillary area has received frequent attention in the literature. However, as a rule, most of the cases described are related to the orbit or the orbito-neurocranial space. Almost no literature exists on the detection and treatment of wooden foreign bodies in the retromaxillary space. The authors present an unusual case of long-term retained wood in this area in a child. The case inspires discussion of the general problem of detecting retained retromaxillary wood, even using modern diagnostic tools in this area and the question of the operative therapy, especially the most favourable surgical access.

Transient expression of synaptogyrin in the ganglionic eminence of the human fetal brain

2000

Summary The ganglionic eminence (GE) representing a conspicuous bulb-like elevation of the telencephalic proliferative zone has recently been shown to be involved in the establishment of cortical connections. This study demonstrates the presence of synaptogyrin-immunoreactivity in a large number of cell bodies of the human GE between 12 and 20 weeks of gestation. From the 20 th week onwards synaptogyrin expression sharply declines. No immunoreactive structures are detectable in the 23 rd week or later. As the GE persists nearly throughout the entire fetal period these results show that its neurochemical features change distinctly in the course of development. The synaptogyrin-immunoreactive…

Quantification of colloid bodies in Oral Lichen Planus and Oral Lichenoid Reaction - A Histochemical Study

2011

Aim: Oral lichen planus and oral lichenoid reaction are familiar keratotic lesions found on the oral mucosa. Colloid bodies can be microscopically appreciated in both these lesions. The aim of this study was to identify as well as examine the frequency of colloid bodies in oral lichen planus and oral lichenoid reaction by histochemical means. Method: The material for the study included 12 formalin-fixed paraffin-embedded tissue blocks (7 oral lichen planus and 5 oral lichenoid reaction), retrieved from the Department of Oral Pathology and Microbiology, MCODS, Manipal. Sections stained with hematoxylin-eosin (H&E) and periodic acid-Schiff (PAS) with diastase to identify, locate and examine t…

Expression of R-3-hydroxybutyrate dehydrogenase, a ketone body converting enzyme in heart and liver mitochondria of ruminant and non-ruminant mammals

1992

1. The properties of rat liver and bovine heart R-3-hydroxybutyrate dehydrogenase (BDH) have been extensively studied in the past 20 years, but little is known concerning the biogenesis and the regulation of this dehydrogenase over different species. 2. In addition, controversial results were often reported concerning the activity, the level and the subcellular location of this enzyme in ruminants. 3. BDH activity found in liver and kidney mitochondria from ruminants (cow and sheep) is low, while it is much higher in rat. 4. However, the enzyme activity is detected in microsomes and in cytosol of liver and of kidney cells from ruminants. These activities are not correlated to ketonaemia lev…
