Staph and Osteoclasts

Staph
and
Osteoclasts

Staphylococcus aureus mediates immunological cross-talk between osteoclasts, cells that are responsible for degrading bone and remodeling the skeletal system. Staph found in infections can “manipulate” osteoclasts and promote bone damage and loss.

Multiplexed Molecular Imaging of Human Kidney

Multiplexed Molecular
Imaging of
Human Kidney

CODEX multiplexed immunofluorescence image of a human kidney tissue section. These data were collected as part of a multimodal imaging study integrating MALDI imaging mass spectrometry and CODEX to discover the relationships between lipid and metabolite distributions and cellular organization in donors with hypertension and type-2 diabetes for the Human Biomolecular Atlas Program (HuBMAP).

COX-2, Human Enzyme

COX-2,
Human Enzyme

Larry Marnett, former Dean of Basic Sciences, was dedicated to his work with COX-2, a human enzyme that is targeted by non-steroidal anti-inflammatory drugs. This image is based on the structure of the NSAID isoxicam when bound to COX-2, a structure that Marnett’s lab determined in 2014. Water molecules mediate a crucial aspect of this interaction at amino acid residues R120 and Y385. Oxicams (including isoxicam) are the only class of NSAIDs for which water-mediated binding to COX-2 is observed. The structure, including the water molecules, is essential for explaining the structure-activity of this series of drugs.

Motor Assembly

Bacterial Flagellar Motor Assembly: The Salmonella flagellar motor, which enables bacterial movement, is shown here with its key components: the C-ring proteins (FliG in red, FliM in yellow, and three FliN in shades of purple), the MS- ring (FliF in blue), the LP-ring (pink), the rod (gray), and the MotAB stator complex (brown).

Zebrafish Eye

Zebrafish
Eye

The eye of a Zebrafish embryo at 72 hours post fertilization was imaged by spinning disk confocal microscopy. The embryo was labeled with Phalloidin-568 to label actin filaments to visualize the action cytoskeleton in the embryonic eye. The image is a projection of a 3D image with the rainbow colors showing the change of the signal through the Z dimension.

Acinetobacter baumannii DNA rearrangement

Acinetobacter
baumannii DNA
rearrangement

Mutations in the genome of A. baumannii increases A. baumannii's cell size and antimicrobial resistance, making it more harmful. This is shown in that the bacteria are a deeper red as they become more virulent.

CcmA Distribution Patterns on Heliobacter pylori

CcmA Distribution
Patterns on
Heliobacter pylori

This dynamic sculpture illustrates the 3D distribution of CcmA proteins on the cell wall surfaces of four H. pylori mutants (with each mutant type shown in a different color under natural light). When black light is introduced, the CcmA protein distribution on each cell becomes visible and begins to glow. Each cell shape is taken from a real cell in the lab, along with its corresponding protein distribution.
