Research into synthetic antibodies offers hope for new diagnostics


January 25, 2011

Antibodies are watchdogs of human health, continuously prowling the body and registering minute changes associated with infection or disease with astonishing acuity. They also serve as biochemical memory banks, faithfully recording information about pathogens they encounter and efficiently storing this data for later use.

Stephen Albert Johnston, Neal Woodbury and their colleagues at the Biodesign Institute at ASU have been exploring mechanisms of antibody activity, particularly the ability of these sentries to bind – with high affinity and specificity – to their protein targets. A more thorough understanding of the antibody universe may lead to a new generation of rapid, low-cost diagnostic tools and speed the delivery of new vaccines and therapeutics. Download Full Image

Borrowing a script from nature, the group has been working to construct synthetic antibodies or synbodies, through a simple method developed in Johnston’s Center for Innovations in Medicine. They have also examined the broad portrait of antibody activity revealed in a sample of blood, harnessing this information for the presymptomatic diagnosis of disease. These immunosignatures, as Johnston has named them, provide a dynamic report card on human health.

In a pair of new papers, the group demonstrated a simple means of improving the binding affinity of synbodies, which are composed of 20 unit chains of amino acids, strung together in random order. They also used random peptide sequences spotted onto glass microarray slides to mine information concerning the active regions or epitopes of naturally occurring antibodies. These two projects recently appeared in the journals PloS ONE and Molecular and Cellular Proteomics, respectively.

While antibodies have been in use for biomedical research for a long time, conventional techniques for producing them have been time consuming and expensive. Normally, antibodies used for research are produced in animals, which respond to a given injected protein by producing a protein-specific antibody, which may then be extracted.

In earlier work, Johnston’s group showed that high-affinity antibody mimics can be produced synthetically by simple means. Their technique turns the traditional production approach on its head. Rather than beginning with a given protein and trying to generate a corresponding antibody, the new method involves building a synthetic antibody first, later determining the protein it effectively binds with, by screening it against a library of potential protein mates.

The first step in this process is to generate random strings of 20 amino acids. Roughly, 10,000 such random peptides are then spotted onto a glass microarray slide. The protein one is seeking an antibody to is screened against this random sequence array and peptides with high binding affinity are identified. Two such peptides can be linked together to form a synbody, whose binding affinity is the product of each separate peptide. In this way, two weakly binding peptides join forces to form a high affinity unit, useful for investigations into the proteome, the vast domain of proteins essential to virtually all biological processes.

In the PloS ONE study, lead author Matthew Greving and his collegues describe a strategy for further refinement of binding affinity in random sequence peptides. 

“The problem,” Johnston explains, is that the microarray contains about 10,000 peptides, but that is less than a quadrillionth of the possible peptides by sequence. So we’re sampling a very small part of the sequence space. ”A consequence of this is that the probability of generating a 20 amino acid sequence, that binds with optimal affinity, is pretty low."

To improve sequence affinity, a lead sequence is first selected. In the study, one such sequence was the 17 amino acid peptide TNF-1, a key regulator of immune cells. The lead sequence is then used as a template from which to generate additional peptide sequences in which a single amino acid at each subsequent position along the peptide chain is replaced with a different amino acid.

Using this method, 96 variant peptides are constructed on a microarray plate. These enhanced variants are screened against a desired protein for binding affinity and a map is produced  displaying this affinity from low to high. The most successful variants can then be assembled into a new high affinity peptide, whose binding strength is the sum of the components.

This simple, algorithmic process can rapidly optimize random sequence peptides, improving their binding affinity by 100 to 1000 times.  The method can also be used to improve the specificity of peptides, enabling the construction of binding agents able to attach to a given protein while excluding unwanted binding targets.

The MCP study asked whether a similar random peptide microarray could assist in the process of epitope mapping, in which the active binding regions of antibodies are identified. Epitope mapping is one method for determining if a given antibody is suitable for a particular application, and a faster, more cost-effective method would be of significant biomedical value.

For these experiments, antibodies of known epitope were screened against random sequence peptides on a microarray.  High affinity peptides were identified and bioinformatics techniques were used to see if the random peptides could help identify the antibody epitopes.

Two techniques were applied; one in which high affinity random sequence peptides were compared side by side with the antibody epitopes they bound with and similarities statistically analyzed. The other method searched the peptides for signature “motifs” – consisting of at least seven amino acids (or two shorter motifs in combination).  

Lead author Rebecca Halperin and colleagues were able to show that statistically useful information on epitopes could indeed be gleaned from such bioinformatic probing, bringing the prospect of high throughput, inexpensive exploration of natural antibodies a step closer.

Johnston stresses the importance of this research. “The paper asks if there are mechanisms to transfer from random sequence space to real sequence space based on antibody binding. No one has explored this as deeply as Rebecca has.”

Further refinement should allow diagnosis of the precise protein sequence causing a given illness, based purely on analysis of immune response.

DUMBLE HONORED TWICE
In a vote of coaches around the nation, Sun Devil throws coach David">http://thesundevils.cstv.com/sports/c-track/mtt/dumble_david00.html">David Dumble was selected as the 2010 USTFCCCA Men’s Division I National Assistant Coach of the Year, both indoors and outdoors. The West Region honoree both indoor and outdoor as well, Dumble has now been selected for the national honor for the fourth and fifth times, respectively, and the first on the men’s side of competition. He was honored for his efforts with the women’s throws three times previously as well.

ACADEMICALLY SOUND: USTFCCCA HONORS MEN
In the classroom, numerous Sun Devils found great success, led by Ryan">http://thesundevils.cstv.com/sports/c-track/mtt/whiting_ryan00.html">Ryan Whiting, who was named the USTFCCCA Division I Indoor & Outdoor Field Scholar of the Year. Whiting, one of 13 Sun Devils to earn national all-academic honors from the USTFCCCA, also led the way for the ASU men, who also were named the USTFCCCA Division I Outdoor Scholar Team of the Year.

PROGRAM RANKING
In 2010, the USTFCCCA began a new award to be handed out annually to the top all-around program in the nation and naming the men’s award after former Arkansas coach, John McDonnell. Based on points earned in national team finishes at the three NCAA events (cross country, indoor track & field and outdoor track & field) with the lowest total winning, the Sun Devil men finished second overall in the inaugural awarding with 30 points while Oregon earned the trophy with 7.5 points. Arizona State, who finished ahead of Northern Arizona (42.5), Florida State (51.0) and Washington (55.0), scored finishes of 19th at the cross country meet, seventh indoors and fourth outdoors. ASU is not in the running for the 2010-11 award as the cross country team did not score as a team at the 2010 championships.

SETTING THE PACE: ENGELHARDT
Senior Ben">http://thesundevils.cstv.com/sports/c-track/mtt/engelhardt_ben00.html">Ben Engelhardt was led the way for the Sun Devil men’s cross country team during the 2010, earning a berth into the NCAA Championships as an individual qualifier where he finished 51st overall in the national meet. An All-West Region honoree (13th place) and Second Team All-Pac-10 selection (14th place), Engelhardt was the team’s top finisher in all but one race on the season and placed in the Top 20 in five races, including 18th at the NCAA Pre-National Meet.

KRAFT LEADS THE WAY
Head Coach Greg">http://thesundevils.cstv.com/sports/c-track/mtt/kraft_greg00.html">Greg Kraft is entering his 15th year as the leader of the Sun Devil program, a tenure that has brought Arizona State back to the top of the standings in both the NCAA and Pac-10 events. Since his hiring, the program has continued to evolve into one of the more well-rounded in the nation with strength on the track and in the field as well as in cross country. Kraft and his staff have worked diligently to reach their goals of championships and success in education and that has not been more clearly seen than in the past five years as the hardware has continued to roll in. His program has annually produced some of the top individuals in the nation with 23 of the program’s 55 individual and relay national titles won since 2004 while both his teams and individual student-athletes have garnered national academic acclaim. Prior to his arrival, the program boasted one NCAA Championship (men’s outdoor track & field, 1977) and one Pac-10 Championship (men’s outdoor track & field, 1981). In the last five years, his Sun Devils have captured four national crowns (2007 women’s indoor and outdoor track & field, 2008 men’s and women’s indoor track & field) and added three Pac-10 Championships (women’s outdoor track & field, 2006-08). Kraft’s teams have finished in the Top 10 of the NCAA Track & Field Championships on 20 occasions in 14 years while the program had done so just 14 times prior to his arrival in Tempe.

LONG TENURE IN TEMPE
As he begins his 15th year at Arizona State, Kraft’s tenure ranks as the second-longest in Sun Devil track & field history and the fourth-longest active streak among all current ASU head coaches. The only coach that has led the track & field program longer than Kraft is legendary coach Senon ‘Baldy’ Castillo, who led the way for 26 years (1954-79). Among current Sun Devil head coaches, Kraft’s 15th year ranks behind John Spini, who is in his 31st year with gymnastics; Sheila McInerney, who is in her 27th year with women’s tennis; and Randy Lein, who is in his 19th year with the men’s golf program.

NEXT TIME OUT
The Sun Devils will send athletes to a pair of competitions next weekend, including a return visit to Albuquerque for the New Mexico Classic (Friday-Saturday) while others will travel north to Flagstaff for the NAU Team Challenge (Saturday).
