Covid-19 Coronavirus Variants Omicron Delta Gamma Beta Alpha Pandemic Virus Disease Mutation
Proteasomes are molecular machines for breaking down proteins called proteolysis, only target proteins that have been marked for destruction called ubiquitin to the target protein, 3d rendering
Textured cells under heavy magnification
orange: RNA primer; red: RNA template; light blue: proofreading riboexonuclease; mid blue: helicase; dark blue: RNA directed RNA polymerase; violet: non structural proteins (NSPs).
Inside protein molecule
Nucleosome, molecular model. 3D illustration. The nucleosome consists of a DNA double helix wrapped around a core of histone proteins.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
3D cartoon and Gaussian surface models, PDB 2j0D, white background.
Liver Fluke Section under light microscope with white background
A ball and stick + ribbons model of beta-secretase - a protein that is important in forming healthy peripheral nerve cells, but is also involved in the onset of Alzheimer's disease.
Biological protein and molecule, 3d rendering. 3D illustration.
p53 (blue) tagged with ubiquitin (yellow) is degraded into small peptides by a proteasome (violett). p53 prevents cancer formation and acts as a guardian of the genome. Mutations in the p53 gene contribute to about half of the cases of human cancer.
This computer-generated image vividly illustrates the invasive Group A Streptococcal bacteria, as they would appear under a microscope. This visual representation helps to understand the microscopic world of Group A Streptococcus and its potential to cause serious diseases.
Gamma secretase protein complex. Multi-subunit intramembrane protease that plays role in processing of proteins. 3D illustration.
Bacteria pathogen - 3d rendered microbiology image. Illustrate of Lactobacillus Bulgaricus Bacteria, Microbacterium Tuberculosis Bacteria (MTB). Medical research, health-care concept. SEM (TEM) scanning view

The cytokin interleukin 11 (IL-11) plays an important role in autoimmune diseases, fibrotic complications, and solid cancers. Blocking IL-11 can extend lifespan and improve health.
A ball and stick + ribbons model of Human Growth Hormone, also known as Somatotropin.
c-Myc and Max transcription factors bound to DNA. 3D illustration. Atoms shown as spheres with conventional color coding.
Endosomes - 3d rendered image of Endosomes are membrane-bound organelles. They are parts of endocytic membrane transport pathway.  Endomembrane system in cells. Bilayer Lipid Membrane. Abstract medical illustration. Microscopic view. Microbiologic research concept.
B-chain pentamer and A-chain subunit (green), 3D cartoon and Gaussian surface model, white background
This footage shows the translation initiation complex, which consists of the ribosomal small subunit, transfer RNA (tRNA), and translation initiation factors. The golden ribbon represents the RNA.
DNA close-up, DNA Molecule Model, DNA Strands, DNA animation
Photomicrograph of rotifer. Rapidly rotating cilia at top of head, internal organs visible. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination.
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.
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.
