Illustration of the formation of metastases : The primary tumour is in the breast. The primary cancer tumour develops : Step 1, the tumour is still small in size Step 2, the tumour has grown, the cancer cells have multiplied and transformed. Step 3, the tumour has grown even more. The cells with irregular nucleus are mature cancer cells (metastases) which will spread to other parts of the body through the blood vessel network. In the case of breast cancer, the metastases can remain dormant for several years in the brain, liver and bones, or can proliferate immediately and form a secondary cancer tumour.

Illustration of the second phase of malaria transmission from one organism to another. The parasites (merozoites) move through blood vessels to the lungs where immune surveillance is lower and blood flow slower. They break out of their envelope (made by the liver). They penetrate red blood cells, ultra rapid transporters that allow them to avoid the filtering spleen. They proliferate in their shelter until, after 48h, they blow up the cell membrane, spread through the blood and quickly parasite other red blood cells to proliferate once more. An immune reaction starts up and the infected person has a high temperature. After a few cycles, the person is tired as the red blood cells no longer carry enough oxygen. Cell residue stuck to blood vessel lining risks blocking the vessels and producing a coma, or even killing the infected person. With each cycle, some merozoites change into asexual male or female gametes who cling to the lining of blood vessels close to the skin and wait for the r

Myocardial infarction, coronary artery with thrombus, atheromatous plaques, treatments. The atheromatous plaques (yellow) in the wall of the coronary artery cause coronary disease. In the zoom of the coronary vessel, a thrombus forms at the bottom right, in contact with the blood by platelet aggregation. Treatments act on platelets to prevent platelet aggregation, on the secretion of aldosterone by the kidneys and adrenals, but also upstream, on the liver by limiting the synthesis of cholesterol at the origin of atheromatous plaques.

Coronavirus replication, CoVid-19, SARS-Cov2. This scientific illustration explains how the 2019 coronavirus replicates thanks to a host cell. FUSION: When the virus reaches the respiratory system by inhalation, it fuses with a host cell thanks to its protein S (spicule), viral surface protein and a membrane receptor of the host cell. TRANSLATION: Viral RNA (positive strand) binds to ribosomes. It is transcribed to form an RNA replicase which will make RNA (negative strand) from RNA (positive strand). TRANSLATION: Viral RNA (positive strand) binds to ribosomes. It is transcribed to form an RNA replicase which will make RNA (negative strand) from RNA (positive strand). TRANSCRIPTION.ET RÉPLICATION: This negative strand is used to make RNA under genomics It allows to replicate viral RNA (positive strand). TRANSLATION:. Thanks to the ribosomes of the host cell, the viral RNA (positive strand) produces the viral proteins (N, M, E and S) which fuse with the endoplasmic membrane. The latter

Hematopoiesis, physiological process allowing the creation and renewal of blood cells or hematocytes. Stem cells come from the red bone marrow of the flat and short bones represented here by the pelvic bone. These stem cells give two types of cells: myeloid stem cells which give the differentiated cells following red blood cells or erythrocytes, platelets, white blood cells or leukocytes (polynuclear and monocytes) and lymphoid stem cells which give white blood cells (lymphocytes, which give NK cells (natural killers), T lymphocytes, B lymphocytes, plasma cells).

Breast cancer and its treatments. A silhouette of a woman with a brain section with the pituitary gland. The pituitary gland stimulates the secretion of estrogens by the ovary (uterus in frontal section), which will bind to the estrogen receptors of cancer cells (bottom center). On the silhouette a mammary gland with the axillary ganglia which relate to it. A first zoom starts from this gland to show the anatomical structure of the mammary gland with a main galactophore channel receiving the lobules, themselves made up of acinus. An enlarged acinus is seen in section. A cancerous tumor is located on the main milk duct. In the foreground, zoom of a blood vessel surrounding cancer cells seen in section the tumor with its numerous vessels in the background. The HER2 receptor (green), EGFR (pink) and the estrogen receptor (orange) are present on the cancer cell whose nucleus is cut to show the mitotic spindle.
