Background The laboratory has previously identified a pathway by which infected human macrophages are induced to kill intracellular mycobacteria rapidly.
Density of newly synthesized plasma membrane proteins in intracellular membranes.
Endophytic parasites may be intracellular, when the fungus or its mycelium plunges into the cells and destroys their contents directly (Olpidium, Lagenidium, Sclerotinia, &c.), but they are far more frequently intercellular, at any rate while young, the mycelium growing in the lacunae between the cells (Peronospora, Uredineae) into which it may send short (Cystopus), or long and branched (Peronospora Calotheca) haustoria, or it extends in the middle lamella (Ustilago), or even in the solid substance of the cell-wall (Botrytis).
Etiology of tuberculosis mycobacterium tuberculosis is an intracellular pathogen.
Externally, the nephridium opens by a straight part of the tube, which is often very wide, and here the intracellular lumen becomes intercellular.
Furthermore we will use intracellular current injection to manipulate the activity of descending neurons, to identify those interneurons that elicit significant changes.
In the blood of the owl resting, intracellular phases of both parasites alternate with active trypaniform ones; and, when in the former condition, Schaudinn considers that the parasites are identical with what have been formerly regarded as distinct Haemosporidia, Halteridium and a Leucocytozoon respectively.
In this way, the same intracellular messenger, calcium, can be used to control all sorts of things without confusing the cell.
Inclusion conjunctivitis is caused by an intracellular organism called Chlamydia trachomatis.
Increasing intracellular calcium can have many health benefits.
Interaction of histamine with receptors on blood vessel, nerve, and tissue cells causes inflammation and the accumulation of intracellular fluid released by the cells.
It also plays a role in the immune system, apparently helping control infection by intracellular parasites.
It appears, however, to be associated with a leucine transporter system across neuronal cell membranes and may increase intracellular GABA.
It displays a type of antibody called immunoglobulin type E (IgE) on its cell surface and participates in the allergic response by releasing histamine from intracellular granules.
Many strains are facultative intracellular parasites which produce endotoxins and enterotoxins.
Methods have been introduced for the purpose of breaking up the bodies of bacteria and setting free the intracellular toxins.
Nephridia always paired, rarely (Pontobdella) forming a network communicating from segment to segment; lumen of nephridia always intracellular, funnels pervious or impervious.
Nephridia generally paired, often very numerous in each segment, in the form of long, much-coiled tubes with intracellular lumen.
No sharp lines can be drawn, however, since many mycelia are intercellular at first and subsequently become intracellular (Ustilagineae), and the various stages doubtless depend on the degrees of resistance which the host tissues are able to offer.
Nystatin however, binds to ergosterol and alters membrane permeability and hence allows leakage of intracellular contents.
Phagocytosis is an uptake mechanism based on a complex rearrangement of the actin cytoskeleton that delivers large extracellular particles into intracellular vacuoles.
The action of these intracellular toxins has in many instances nothing characteristic, but is merely in the direction of producing fever and interfering with the vital processes of the body generally, these disturbances often going on to a fatal result.
The advantage of this model system stems from the distinctive morphology of WPB allowing them to be distinguished from other intracellular organelles.
The nephridia in this group are invariably coiled tubes with an intracellular lumen and nearly invariably open into the coelom by a funnel.
The parasites are either free or intracellular.
The plasma membrane envelopes the particle and buds off to form an intracellular vesicle, the phagosome.
The selected CD4 cells are washed on a magnet tray and then lysed to release intracellular ATP.
The strategy is based on the latest research that suggests creatine's benefits are proportional to intracellular creatine concentrations [13] .
The tetrahedral structuring possesses five-fold symmetry, which prevents easy freezing in line with the pronounced supercooling found for intracellular water.
Their replication strategy like that of viruses - they are obligate intracellular parasites.
These are a transient intracellular form, either rapidly infecting new erythrocytes to complete the erythrocytic cycle, or dying.
These cells then display a Treg phenotype and function as determined by FACS, T cell proliferation assays, ELISA and intracellular cytokine staining.
They consist of a pair of tubules with an intracellular lumen running up the sides of the body, at times merely sinuous, at others considerably convoluted.
They did not however see any differences in the intracellular ionic calcium levels with normal neutrophils.
This excitation requires brief tetanic stimulation of parallel fibers and is modified by intracellular factors such as activity in the climbing fiber.
This interest in the intracellular pH regulation subsequently included studies on the changes induced by hypoxia, lactate and temperature on intracellular pH.
This pigment is usually intracellular, but may be found lying free in the intercellular substance, and is generally in the form of fine granules of a yellowish-brown or brown-black colour.
This recent microbiological research study gives new insight to the intracellular control mechanisms of platelets.
Toxoplasmosis-A parasitic infection caused by the intracellular protozoan Toxoplasmosis gondii.
Unlike viruses non-viral vectors are not as well equipped to overcome these intracellular barriers.
We are currently studying the role of these isoforms in different intracellular signaling pathways.
With regard to the nature of intracellular toxins, there is even greater difficulty in the investigation and still less is known.
Within the cells there are numerous intracellular compartments that operate more or less autonomously from the rest of the cell.
X c is a measure of the volume of the cell membrane capacitance and an indirect measure of intracellular fluid volume.
