Innate and acquired immunity in myocardial adaptation to ischemia - possible therapeutic gains?

Atherosclerosis is our major cause of morbidity and mortality, causing cerebral stroke, myocardial infarction, lower extremity gangrene, renal infarctions etc. Atherosclerosis is a chronic process involving both innate and adaptive immunity in its develop ment, and is a subject for attempts of im...

Dynamics of a retinal synapse, as studied by simultaneous measurement of presynaptic capacitance and postsynaptic current

A major challenge in neuroscience is to understand how the physiological and biophysical properties of cells and synapses in a sensory system give rise to functional circuits that transform the neuronal representations of sensory stimuli. The key question is to determine how specific molecular m...

Molecular and electrophysiological characterization of the GnRH systems in Atlantic cod

Teleosts are unique among vertebrates regarding neural control of the adenohypophysis. The cells are directly innervated instead of receiving their input through a portal system. Furthermore, the distribution of the different cell types in the adenohypoph ysis in teleosts is highly regionalized, ...

An Environmentally Induced FRQ-Independent 24 hour Rhythm in Neurospora crassa

Circadian rhythms (from latin circa, about; and dies, day) play an important role in the adaptation of organisms to their natural environment. It is assumed that by measuring day length, the circadian clock participates in the initiation of important dail y processes, for example sleep or activit...

Androgens and growth of previtellogenic oocytes in Atlantic cod: Identification and pattern of differentially expressed genes and proteins

The overall objective of the proposed project is to study the role and effect of androgens (e.g. 11-ketotestosterone; 11-KT) on the growth of previtellogenic oocytes through the characterization of androgen-responsive ovarian genes and proteins. Thus incr easing our understanding on the hormonal ...

Interactions between foreign DNA and SECs (scavenger endothelial cells) in vitro and in vivo

Nucleic acid (NA) molecules (DNA and RNA) in food/feed are taken up from the intestines and circulate in the bloodstream of mammals. Isogenic NA shed from apoptotic and necrotic cells are also released into the blood circulation. DNA is usually very rapid ly cleared from the bloodstream, and degr...

ELECTROPHYSIOLOGICAL CHARACTERIZATION OF TWO GLUTAMINE TRANSPORTERS IN HETEROLOGOUS EXPRESSION SYSTEMS AND IN VIVO

We have molecularly identified SN1, a glutamine transporter, and demonstrated its capability of releasing glutamine at physiological conditions. The translocation of glutamine by SN1 is energized by coupling to Na+ in symport and H+ in antiport. Such elec troneutral transport allows the transport...

Emergence of functional neural networks in the developing brain: A functional imaging study

The current view of brain development is that neuronal circuits are formed through an interaction between two fundamentally different mechanisms. First, growing axons are targeted to specific regions by molecular guidance and recognition cues. Second, on going neuronal activity regulates the str...

Cellular mechanisms of heart failure

In cardiac myocytes, contraction is triggered by a transient increase in intracellular Ca2+ levels. Depolarization causes Ca2+ entry through L-type Ca2+ channels, which in turn triggers release of Ca2+ from the sarcoplasmic reticulum (SR). This process is referred to as Ca2+-induced Ca2+ release...
