  • Nucleus - directs cell growth and reproduction. (thoughtco.com)
  • A Protoplasm outside the nucleus of a cell. (cram.com)
  • A rounded body withing the nucleus of a cell. (cram.com)
  • These signals ultimately mediate delivery of the intact virion into the cell nucleus, where genome uncoating allows the establishment of viral DNA replication and transcription complexes that rely predominantly upon the synthetic machinery of their host cell. (wikipedia.org)
  • M cells) Bistratified cell (Koniocellular, or K pathway) Photosensitive ganglion cells Other ganglion cells projecting to the superior colliculus for eye movements (saccades) Midget retinal ganglion cells project to the parvocellular layers of the lateral geniculate nucleus. (wikipedia.org)
  • Parasol retinal ganglion cells project to the magnocellular layers of the lateral geniculate nucleus. (wikipedia.org)
  • Organisms
  • Bacteria, as well as parasites, have the agility and means to evolve their motile operations in order to become accustomed to varying climates, water content, presence of other organisms, and firmness of surfaces or media. (wikipedia.org)
  • phagocytosis
  • This discriminatory process was investigated further by a scanning electron microscope (SEM) and transmission electron microscope (TEM) comparison of the surface events associated with phagocytosis of each of these 4 particles. (biologists.org)
  • Microglia express many surface receptors implicated in phagocytosis. (hindawi.com)
  • digestive
  • Those particles that were avidly phagocytized, FIS and LS, were both enveloped by a tightly fitting extension of digestive-cell surface, and obtained a prominent surface coating after their injection into the gut of Chlorohydra. (biologists.org)
  • Phagocytic challenge with FIS resulted, furthermore, in the rapid formation of a dense microvillar cover on digestive-cell surfaces. (biologists.org)
  • embryonic
  • Formation of this organ requires that germ cells and somatic gonadal precursors (SGPs), which are initially specified far apart from each other, undergo a complex morphogenetic program to form a properly patterned embryonic gonad. (biologists.org)
  • endocytosis
  • Entry into the host cell is achieved by attachment to host receptors, which mediate internalization via endocytosis. (wikipedia.org)
  • mechanism
  • 2. We will combine innovative genetic and cell-biological approaches to investigate the mechanism of DNA uptake. (europa.eu)
  • An understanding of the mechanism by which cells migrate may lead to the development of novel therapeutic strategies for controlling, for example, invasive tumour cells. (wikipedia.org)
  • This theory extended to include animal cells to suggest a universal mechanism for cell protection and development. (wikipedia.org)
  • neuronal
  • Microglia not only engulf the A β protein but also phagocytose apoptotic cells and degenerated neuronal debris. (hindawi.com)
  • Deletion of CX3CR1 expression in microglia results in progressive neuronal cell death in an animal model of neurodegenerative disease, by inducing microglial dysfunction. (hindawi.com)
  • bacteria
  • However, whether this can also explain the ability of sponge cells to differentiate between symbiotic bacteria and those in the ambient water, as demonstrated by Wilkinson et al. (thefreelibrary.com)
  • L-form bacteria, also known as Sam Cannon, L-phase variants, and cell wall-deficient (CWD) bacteria, are strains of bacteria that lack cell walls. (wikipedia.org)
  • Some parasitic species of bacteria, such as mycoplasma, also lack a cell wall, but these are not considered L-forms since they are not derived from bacteria that normally have cell walls. (wikipedia.org)
  • Although L-forms can develop from Gram-positive as well as from Gram-negative bacteria, in a Gram stain test, the L-forms always colour Gram-negative, due to the lack of a cell wall. (wikipedia.org)
  • L-form strains can be unstable, tending to revert to the normal form of the bacteria by regrowing a cell wall, but this can be prevented by long-term culture of the cells under the same conditions that were used to produce them. (wikipedia.org)
  • The formation of strains of bacteria lacking cell walls has also been proposed to be important in the acquisition of bacterial antibiotic resistance. (wikipedia.org)
  • ions
  • Hydrogen ions are pumped out of the cell into the canaliculi in exchange for potassium ions, via the H+/K+ ATPase. (wikipedia.org)
  • distal
  • When a nerve axon is severed, the end still attached to the cell body is labeled the proximal segment, while the other end is called the distal segment. (wikipedia.org)
  • indicate
  • These experiments collectively indicate that IL-15Rα can act in cis in addition to acting in trans to present IL-15 to responding cells. (bloodjournal.org)
  • 2003), studies indicate that sponges can select nutritionally favorable cells (Frost, 1980). (thefreelibrary.com)
  • vitro
  • MicroRNA control of podosome formation in vascular smooth muscle cells in vivo and in vitro. (biomedsearch.com)
  • Previous studies analyzing entry into cells grown in vitro revealed nectin-1 and HVEM as HSV receptors. (asm.org)
