The IGBB logo features a stylized "pinwheel" to the left of the letters IGBB in caps in a modified Bank Gothic Pro font.
The six-part "pinwheel" in the IGBB logo is:
- A symbol of lab unity as it shows "parts" coming together to make a "whole."
- A flower or three-leaf clover representing (a) plants, important subjects of our research, (b) life in general, and (c) the life sciences (biology).
- A set of chromosomes being moved towards the center of a cell.
- The Sun - another symbol of life.
- A protein composed of six subunits (e.g., a protein pore).
- Three foxes putting their heads together. The fox is a symbol of cleverness in Western folklore. Since the IGBB is organized into three service groups (Genomics, Proteomics/Metabolomics, and Biocomputing/Computational Biology), the foxes could represent the three disciplines working together.
- A scientist jumping for joy after making an important discovery.
- A windmill, the primary symbol associated with Cervantes' famous character Don Quixote - Like Don Quixote, scientists must be willing to attack 'wicked giants' (e.g., ignorance, racism, sexism, intolerance, use of the term 'science' in the promotion of non-scientific causes), champion worthy causes (e.g., education, intellectual freedom, human rights, environmental responsibility), and remain optimistic in the face of defeat (e.g., most days in the lab). Hopefully, however, the average scientist can accomplish these tasks without becoming delusional (a problem that squashed Quixote's dreams of becoming a plant molecular biologist).
- A DNA double-helix or protein in cross section.
- Antibodies binding to a protein.
- Whatever you want it to be.

Hodgkin's and many diverse non-Hodgkin's lymphomas overexpress the Hodgkin's disease antigen CD30 (CD30(hi)), a tumor necrosis factor receptor II family member. Here we show that chicken Marek's disease (MD) lymphoma cells are also CD30(hi) and are a unique natural model for CD30(hi) lymphoma. Chicken CD30 resembles an ancestral form, and we identify a previously undescribed potential cytoplasmic signaling domain conserved in chicken, human, and mouse CD30. Our phylogeneic analysis defines a relationship between the structures of human and mouse CD30 and confirms that mouse CD30 represents the ancestral mammalian gene structure. CD30 expression by MD virus (MDV)-transformed lymphocytes correlates with expression of the MDV Meq putative oncogene (a c-Jun homologue) in vivo. The chicken CD30 promoter has 15 predicted high-stringency Meq-binding transcription factor recognition motifs, and Meq enhances transcription from the CD30 promoter in vitro. Plasma proteomics identified a soluble form of CD30. CD30 overexpression is evolutionarily conserved and defines one class of neoplastic transformation events, regardless of etiology. We propose that CD30 is a component of a critical intracellular signaling pathway perturbed in neoplastic transformation. Specific anti-CD30 Igs occurred after infection of genetically MD-resistant chickens with oncogenic MDV, suggesting immunity to CD30 could play a role in MD lymphoma regression.
