TNF is a homotrimeric cytokine, a cell signaling protein, involved in inflammation processes. TNF main role is the regulation of immune cells. PDB entry 1tnf
Diffuse large B-cell lymphoma, or DLBCL, is a cancer that starts in white blood cells called lymphocytes.
Biological protein and molecule, 3d rendering. 3D illustration.
Natural agate surfaces, suitable for backgrounds and wallpapers.
Intracellular transport, kinesin motor proteins, orange, transport molecules moving across microtubules, 3D illustration
plant Stem of Nymphaea tetragona T.S. under light mircoscope with white background
Complement component 3, often simply called C3, is a protein of the immune system. It plays a central role in the complement system and contributes to innate immunity. 3D cartoon and Gaussian surface models with differently colored protein chains, white background.
Monkeypox Virus. 3D Render
Bacterial multidrug efflux pumps (E-CmeB) expel antibiotics from inside the bacterium (bottom): ciprofloxacin (yellow), chloramphenicol (violet), ampicillin (red).
Pleomorphic liposarcoma. Site: Neck. Pleomorphic liposarcoma is a rare subtype of fat cell cancer in the body. It is a rare and very malignant type of tumor that usually arises from fat cells and deep soft tissues of the upper and lower extremities (shoulder, arms, legs, and thighs).

Focal nodular hyperplasia (FNH) is a benign liver lesion that is composed of a proliferation of hyperplastic hepatocytes surrounding a central stellate scar. Typically, FNH is a solitary lesion that is more commonly seen in women.
PAPS Smear study of a young women under microscopy showing Atrophic changes in uterus which is unusual at young age.
Squash preparation of onion root tip cells stained to reveal chromosomes, Bright field illumination, light microscopy. This image was taken with the X40 objective lens. Depth of focus is extremely low at this magnification. Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced. The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Metastatic plasmacytoma, metastatic undifferentiated sarcoma. Microscopically show cellular material of mostly plasmacytiod cells. atypical mitoses are present. plasma cell tumor.
Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.
The study of plant tissues under the microscope in the laboratory.
Amazing Colorful Agate Crystal stone cross texture background.
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.
Myxoid liposarcoma. Myxoid/round cell liposarcoma, or MRCLS, is one of several types of liposarcoma. Liposarcoma is a rare cancer that grows in the cells that store fat in the body. MRCLS usually grows in the arms and legs. These tumors grow slowly, and they can spread to other parts of the body
SARS-CoV-2 ORF3a is a putative viral ion channel implicated in autophagy inhibition, inflammasome activation and apoptosis. 3D cartoon and Gaussian surface models, based on PDB 7kjr, white background.
Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens. Depth of focus is extremely shallow (just a few microns). Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.
Microscopic close view of high vaginal swab Gram stain smear, 100x. diagnosis of Bacterial vaginosis (BV).
Photomicrograph of newly hatched freshwater leech. Note multiple eyes at head and second attachment sucker at tail. Body length approx. 3 mm. Live specimen. Wet mount, 5X objective, transmitted brightfield illumination.
