36161167The lubber grasshopper, found throughout the southern United States, is frequently used in biology classes to teach students about the respiratory system of insects. Unlike mammals, which have red blood cells that carry oxygen throughout the body, insects have breathing tubes that carry air through their exoskeleton directly to where it's needed. This image shows the breathing tubes embedded in the weblike sheath cells that cover developing egg chambers.

36191091After multiplying inside a host cell, the stringlike Ebola virus is emerging to infect more cells. Ebola is a rare, often fatal disease that occurs primarily in tropical regions of sub-Saharan Africa. The virus is believed to spread to humans through contact with wild animals, especially fruit bats. It can be transmitted between one person and another through bodily fluids.

3400747Blood vessels at the back of the eye (retina) are used to diagnose glaucoma and diabetic eye disease. They also display characteristic changes in people with high blood pressure. In the image, the vessels appear green. It's not actually the vessels that are stained green, but rather filaments of a protein called actin that wraps around the vessels. Most of the red blood cells were replaced by fluid as the tissue was prepared for the microscope. The tiny red dots are red blood cells that remain in the vessels. The image was captured using confocal and 2-photon excitation microscopy for a project related to neurofibromatosis.12/23/2020 8:25:40 PM12/23/2020 8:25:40 PMType    Name    Media Type    File Size    Modified NCMIR_vasculature1    High 381 KB 6/3/2016 3:28 PM aamishral2 (NIH/NIGMS) [C The tiny red dots are red blood STS_ListItem_DocumentLibraryhttps://images.nigms.nih.gov/PublicAssets/Forms/AllItems.aspx4060https://images.nigms.nih.govhtmlTruehttps://imagesadmin.nigms.nih.gov{1233873B-4276-4C11-861B-FE6A348B950C}Sharepoint.DocumentSet~sitecollection/_catalogs/masterpage/Display Templates/Search/Item_PublicAsset.js3131

2318587Pretty in pink, the enzyme histone deacetylase (HDA6) stands out against a background of blue-tinted DNA in the nucleus of an <i>Arabidopsis</i> plant cell. Here, HDA6 concentrates in the nucleolus (top center), where ribosomal RNA genes reside. The enzyme silences the ribosomal RNA genes from one parent while those from the other parent remain active. This chromosome-specific silencing of ribosomal RNA genes is an unusual phenomenon observed in hybrid plants.

3604965Along with blood vessels (red) and nerve cells (green), this mouse brain shows abnormal protein clumps known as plaques (blue). These plaques multiply in the brains of people with Alzheimer's disease and are associated with the memory impairment characteristic of the disease. Because mice have genomes nearly identical to our own, they are used to study both the genetic and environmental factors that trigger Alzheimer's disease. Experimental treatments are also tested in mice to identify the best potential therapies for human patients.

2514816HIV is a retrovirus, a type of virus that carries its genetic material not as DNA but as RNA. Long before anyone had heard of HIV, researchers in labs all over the world studied retroviruses, tracing out their life cycle and identifying the key proteins the viruses use to infect cells. When HIV was identified as a retrovirus, these studies gave AIDS researchers an immediate jump-start. The previously identified viral proteins became initial drug targets.

36561171A fruit fly ovary, shown here, contains as many as 20 eggs. Fruit flies are not merely tiny insects that buzz around overripe fruit--they are a venerable scientific tool. Research on the flies has shed light on many aspects of human biology, including biological rhythms, learning, memory and neurodegenerative diseases. Another reason fruit flies are so useful in a lab (and so successful in fruit bowls) is that they reproduce rapidly. About three generations can be studied in a single month.

3392742Stained glomeruli in the kidney. The kidney is an essential organ responsible for disposing wastes from the body and for maintaining healthy ion levels in the blood. It works like a purifier by pulling break-down products of metabolism, such as urea and ammonium, from the blood stream for excretion in urine. The glomerulus is a structure that helps filter the waste compounds from the blood. It consists of a network of capillaries enclosed within a Bowman's capsule of a nephron, which is the structure in which ions exit or re-enter the blood in the kidney.12/23/2020 8:07:21 PM12/23/2020 8:07:21 PMType    Name    Media Type    File Size    Modified NCMIR_kidney_glomereolus_L    Low 34 KB 6/3/2016 3:28 PM aamishral2 (NIH/NIGMS) [C STS_ListItem_DocumentLibraryhttps://images.nigms.nih.gov/PublicAssets/Forms/AllItems.aspx4580https://images.nigms.nih.govhtmlTruehttps://imagesadmin.nigms.nih.gov{91D93B75-49F2-41DB-9621-4ABF190E134E}Sharepoint.DocumentSet~sitecollection/_catalogs/masterpage/Display Templates/Search/Item_PublicAsset.js3131
37711039Viruses have been the foes of animals and other organisms for time immemorial. For almost as long, they've stayed well hidden from view because they are so tiny (they aren't even cells, so scientists call the individual virus a "particle"). This image shows a molecular model of a particle of the Rous sarcoma virus, a virus that infects and sometimes causes cancer in chickens. In the background is a photo of red blood cells. The particle shown is "immature" (not yet capable of infecting new cells) because it has just budded from an infected chicken cell and entered the bird's bloodstream. The outer shell of the immature virus is made up of a regular assembly of large proteins (shown in red) that are linked together with short protein molecules called peptides (green). This outer shell covers and protects the proteins (blue) that form the inner shell of the particle. But as you can see, the protective armor of the immature virus contains gaping holes. As the particle matures, the short peptides are removed and the large proteins rearrange, fusing together into a solid sphere capable of infecting new cells. While still immature, the particle is vulnerable to drugs that block its development. Knowing the structure of the immature particle may help scientists develop better medications against RSV and similar viruses in humans. Scientists used sophisticated computational tools to reconstruct the RSV atomic structure by crunching various data on the RSV proteins to simulate the entire structure of immature RSV. For more on RSV and how researchers revealed its delicate structure, see the NIH director's blog post <a href="https://directorsblog.nih.gov/2016/04/14/snapshots-of-life-imperfect-but-beautiful-intruder/">Snapshots of Life: Imperfect but Beautiful Intruder.</a>12/17/2020 6:39:16 PM12/17/2020 6:39:16 PMType    Name    Media Type    File Size    Modified Imperfect_intruder_for_NIH    High 9721 KB 6/3/2016 3:41 PM aamishral2 (NIH/NIGMS) [C STS_ListItem_DocumentLibraryhttps://images.nigms.nih.gov/PublicAssets/Forms/AllItems.aspx37150https://images.nigms.nih.govhtmlTruehttps://imagesadmin.nigms.nih.gov{A147967A-CD83-453D-8FF9-DC930253A9F5}Sharepoint.DocumentSet~sitecollection/_catalogs/masterpage/Display Templates/Search/Item_PublicAsset.js3131

7004359777Protein kinases—enzymes that add phosphate groups to molecules—are cancer chemotherapy targets because they play significant roles in almost all aspects of cell function, are tightly regulated, and contribute to the development of cancer and other diseases if any alterations to their regulation occur. Genetic abnormalities affecting the c-Abl tyrosine kinase are linked to chronic myelogenous leukemia, a cancer of immature cells in the bone marrow. In the noncancerous form of the protein, binding of a myristoyl group to the kinase domain inhibits the activity of the protein until it is needed (top left shows the inactive form, top right shows the open and active form). The cancerous variant of the protein, called Bcr-Abl, lacks this autoinhibitory myristoyl group and is continually active (bottom).

65191059During cell division, cells physically divide after separating their genetic material to create two daughter cells that are genetically identical to the parent cell. This process is important so that new cells can grow and develop. In this image, a human fibroblast cell—a type of connective tissue cell that plays a key role in wound healing and tissue repair—is dividing into two daughter cells. A cell protein called actin appears gray, the myosin II (part of the family of motor proteins responsible for muscle contractions) appears green, and DNA appears magenta. 12/22/2020 4:11:34 PM12/22/2020 4:11:34 PMType    Name    Media Type    File Size    Modified Fibroblast Division_HIghRes    High 3066 KB 11/6/2019 10:20 AM Harris, Donald (NIH/NIGMS) [C STS_ListItem_DocumentLibraryhttps://images.nigms.nih.gov/PublicAssets/Forms/AllItems.aspx46100https://images.nigms.nih.govhtmlTruehttps://imagesadmin.nigms.nih.gov{D58E532F-7578-4EC5-8E98-64840654F119}Sharepoint.DocumentSet~sitecollection/_catalogs/masterpage/Display Templates/Search/Item_PublicAsset.js3131
2784722Cytoplasmic linker protein (CLIP)-170 is a microtubule plus-end-tracking protein that regulates microtubule dynamics and links microtubule ends to different intracellular structures. In this movie, the gene for CLIP-170 has been fused with green fluorescent protein (GFP). When the protein is expressed in cells, the activities can be monitored in real time. Here, you can see CLIP-170 streaming towards the edges of the cell.9/4/2020 7:36:43 PM9/4/2020 7:36:43 PMType    Name    Media Type    File Size    Modified 2784_Microtubule_dynamics_in_real_time_S    Low 61 KB 3/29/2019 10:52 AM Constantinides, Stephen (NIH/NIGMS STS_ListItem_DocumentLibraryhttps://images.nigms.nih.gov/PublicAssets/Forms/AllItems.aspx47160https://images.nigms.nih.govhtmlTruehttps://imagesadmin.nigms.nih.gov{4781051C-2EC7-46D6-95BC-529D28314966}Sharepoint.DocumentSet~sitecollection/_catalogs/masterpage/Display Templates/Search/Item_PublicAsset.js3131
68011259A macrophage—a type of immune cell that engulfs invaders—“eats” and is activated by a “two-faced” Janus particle. The particle is called “two-faced” because each of its two hemispheres is coated with a different type of molecule, shown here in red and cyan. During macrophage activation, a transcription factor tagged with a green fluorescence protein (NF-κB) gradually moves from the cell’s cytoplasm into its nucleus and causes DNA transcription. The distribution of molecules on “two-faced” Janus particles can be altered to control the activation of immune cells. Details on this “geometric manipulation” strategy can be found in the <em> Proceedings of the National Academy of Sciences</em> paper <a href="https://www.pnas.org/content/116/50/25106.long">"Geometrical reorganization of Dectin-1 and TLR2 on single phagosomes alters their synergistic immune signaling" </a> by Li et al. and the <em> Scientific Reports</em> paper<a href="https://www.nature.com/articles/s41598-021-92910-9"> "Spatial organization of FcγR and TLR2/1 on phagosome membranes differentially regulates their synergistic and inhibitory receptor crosstalk"</a> by Li et al.
