Nucleosome structure. Structure of an oligonucleosome, showing the packaging of DNA in chromosomes. 3D illustration.

A ball and stick + ribbons model of human Interleukin 2 or IL-2. Interleukin is a hormone which acts as a signalling molecule for the immune system.

Copper(II) sulfate with molecular structure. Chemical ingredient used in medical and public health issues.

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Immunotherapy of Alzheimer's disease: Monoclonal antibody (light blue) bound to an amyloid beta peptide (orange), that is aggregated to amyloid beta fibrils, which build up amyloid plaques.

DNA mutation, a mutation is a change in a DNA sequence, mutations can result from DNA copying mistakes made during cell division.

DNA Helix - 3d rendered image. Genetic research concept. Complex spiral structure illustration. Medical, science, genetic biotechnology, gene cell, chromosome idea. DNA strands on dark background . Science nanotechnology.

Dna structure on science background. 3d illustration

After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

Collagen protein molecule. Molecular model. 3D rendering. Illustration

A model of an Enhanceosome protein complex binding to a strand of DNA. This enhanceosome reacts to infection by viruses by accelerating the production of human interferon and triggering the defenses of the immune system.

The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor has a strong effect on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

$Antibodies conjugated with drugs at the FC region are designed to attach a drug to the FC region of the antibody. This technology leverages the specificity of antibodies to deliver the drug directly to target cells. As a result, it can enhance the drug's effectiveness and reduce side effects. This approach is particularly promising in cancer treatment and therapies for autoimmune diseases.\n\nThis image was not created by AI.$

Spike glycoprotein homotrimer, a main target for neutralization antibody, to bind its receptor, ACE2, and mediate membrane fusion and virus entry. 3D cartoon and Gaussian surface models, white background.

Macrophotograph of the structure of DNA: The double helical DNA molecule with a detailed view of the nucleotides. Butterfly dna. This macrophotograph is a magnified image of the structure of DNA, allowing us to view the details of the double helix and the nucleotides that make up the genetic code. The background of the image is dark, which highlights the light strands of DNA and creates a contrast that emphasizes the complexity and beauty of the DNA molecule. This image can be used for scientific, educational or medical purposes and to illustrate topics related to genetics, biology and medical research.
