Neuron with neurofibrillary degeneration process, senile plaque, treatments. Central nervous system neuron affected by abnormal cleavage of APP (Amyloid Precursor Protein) to form senile plaque (yellow). The tau protein normally stabilizing the microtubules of the neuron phosphorylises abnormally and forms tangles (green): neurofibrillary degeneration (NFD). Cholinergic and glutamatergic neurons. Butrycholinesterases (orange), acetylcholinesterase (yellow) and NMDA (yellow) are treatment targets.

A long terme, les cellules souches adultes pourraient s'averer etre le meilleur choix pour la therapie cellulaire. Leurs avantages comprennent : l'absence de problemes de rejet immunitaire, une plus faible predisposition a favoriser les tumeurs, et leur disponibilite dans les tissus adultes. Elles peuvent etre recueillies chez le patient, cultivees et multipliees en nombre suffisant pour traiter une maladie ou des lesions.

Viruses can only multiply within living cells, by replicating their nucleic acid. The infection of a cell by a virus, then the multiplication of the virus can be summarized in different stages. 1. Adsorption of the virus in contact with the membrane of the infected cell, thanks to specific receptors 2. Penetration into the cell 3. Decapsidation (release of the nucleic acid) 4. Replication of the viral genome 5. Synthesis of viral proteins 6 Assembly and encapsidation of the viral particles produced 7. Release of the new viruses from the host cell

Tuberculosis, which results from an infection with Mycobacterium tuberculosis, can be cured with a combination of first-line drugs taken daily for several months. Shown here are the four drugs in the standard regimen of first-line drugs. Also shown are the dates these four drugs were discovered all more than 40 years ago.

The allergic reaction has two phases. When the body comes into contact with a certain allergen for the very first time, it becomes primed or sensitized to react against the certain substance. Macrophages (in blue) phagocytose the allergen particles, then pass on information about the allergen to the B lymphocytes, which produce IgE antibodies. The antibodies bind to basophils and mast cells. At the next encounter with this allergen, the allergic process is activated -- the allergen binds to the IgE antibodies, triggering the mast cell and basophils to release histamine that orchestrates the allergic reaction (here, skin rash).

Didactic illustration representing the moving earth, or the movement in the asthenosphere and the lithosphere.The lithosphere is rigid and solid, therefore brittle while the asthenosphere is solid, but ductile, it deforms without breaking. asthenosphere has an upward movement and sides, which pushes the lithosphere drawing ridges and pits.

Dopamine neurons and synapse. Representation of the connection between two dopamine neurons at the synapse to pass the message (nerve impulse from one neuron to another) and zoom on the synapse. Here they are dopamine neurons (reward system of the brain). Excitatory neurotransmitters (acetylcholine) that can bind to multiple types of receptors located at different locations on neurons are reported to increase the electrical activity of dopamine neurons in the reward system. Since nicotine receptors are subclasses of acetylcholine receptors, they also increase the electrical activity of dopamine neurons in the reward system. (Pleasure felt when smoking a cigarette).
