Self-Propagating Calcifying Nanoparticles as a Unique Entity

Nanobac Announces Peer Reviewed Publication Verifying Self-Propagating Calcifying Nanoparticles as a Unique Entity

"CNPs" Hypothesized to Resemble Prions
TAMPA, FL, Apr 08, 2008 (MARKET WIRE via COMTEX) -- Nanobac Pharmaceuticals, Inc.NNBP ("Nanobac" or "the Company") announces the multicenter publication of independent research, which reports on the characterization of calcifying nanoparticles (CNPs), formerly known as "nanobacteria," as self-propagating mineral protein complexes. The study was led by a leading French microbiologist, the esteemed professor Didier Raoult (Raoult et al, PLoS Pathogens, February 2008, volume 4, issue 2).

The authors undertook a comprehensive analysis of CNPs utilizing a Nanobacterium strain provided by Nanobac's Chief Research and Science Officer Dr. Olavi Kajander. Their goal was to gain better insight into "such a propagating calcifying agent putatively endowed with pathogenic properties." To address this question, the researchers examined CNPs' propagation conditions, susceptibility to various chemical and physical treatments and their effect on cell viability. CNPs' nucleic acid and proteomic content were also analyzed.

Dr. Kajander stated: "The Raoult study confirms the presence of protein-mineral complexes, consistent with complexes published in Nanobac's Patent Applications, which characterized numerous proteins including fetuin, that the French group studied. The group also hypothesized the conformational change of the proteins being similar to those observed in prions, confirming our position. The study also confirmed that the Company's patented 8D10 antibody effectively detected CNPs as a unique pathogen."

"This work has significant diagnostic implications and supports our findings. The published paper should end discussion about whether CNPs exist, and shift the focus on what they really are and what role they play in various diseases," said Dr. Benedict Maniscalco, Co-Chairman and Chief Medical Officer of Nanobac Pharmaceuticals.

About Pathologic Calcific Diseases
Irregular calcium deposits are implicated in inflammatory diseases such as heart disease, prostatitis and arthritis, and stone forming diseases such as kidney and gall stones. The impact on the health care delivery system could be substantial given that billions of dollars are spent each year on treating diseases associated with CNPs. The company is well positioned to take advantage of numerous diagnostic and therapeutic opportunities in these sectors.

Association of Nanoparticle and Kidney Stone Formation

Nanobac Announces Publication of Association of Nanoparticle and Kidney Stone Formation

Results May Change Approach to Medical Management of Kidney Stones

Last update: 11:28 a.m. EST Feb. 19, 2008

TAMPA, FL, Feb 19, 2008 (MARKET WIRE via COMTEX) -- Nanobac Pharmaceuticals Inc. ("Nanobac" or "the Company") announces publication in the International Journal of Nanomedicine research that scientists from the University of California San Francisco collaborating with Nanobac scientists at NASA's Johnson Space Center have concluded demonstrating that calcium deposits in the human kidney called Randall's Plaque may in fact be Calcifying Nano Particles (CNPs, also referred to as nanobacteria) which lead to the formation of Kidney Stones.

The study, led by Marshall Stoller M.D. of UCSF and Neva Ciftcioglu, formerly Nanobac's Director of Science at NASA Johnson Space Center, found that CNPs were identified and cultured from Randall's Plaques and detected by Nanobac's proprietary diagnostics. This could represent potential new early diagnosis and treatment opportunities for patients who suffer from Kidney Stones.

Dr. Olavi Kajander, Nanobac's Chief Research and Science Officer, stated: "A strong link was found between the presence of Randall's Plaques and the detection of CNPs. These results suggest new insights into the etiology of Randall's Plaque formation, and will help us understand the pathogenesis of stone formation. Further studies on this topic may lead to new approaches on early diagnosis and novel medical therapies of kidney stone formation."

Objectives: Randall initially described calcified subepithelial papillary plaques, which he hypothesized as nidi for urinary calculi. The discovery of calcifying nanoparticles (CNP), also referred to as nanobacteria, in calcified soft tissues has raised another hypothesis about their possible involvement in urinary stone formation. This research is the first attempt to investigate the potential association of these two hypotheses.

Methods: We collected renal papilla and blood samples from 17 human patients who had undergone laparoscopic nephrectomy. Immunohistochemical staining (IHS) was applied using monoclonal antibody (mAb) against CNP. Homogenized papillary tissues and serum samples were cultured for CNP. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were performed on papillary samples. Serum samples were tested for CNP antigen and antibody with enzyme-linked immunosorbent assay (ELISA).

Results: Randall’s plaques (RP) were visible on gross inspection in 11 out of 17 samples. IHS was positive for CNP antigen in 8 of the visually positive samples, but in only 1 of the remaining samples. SEM revealed spherical apatite-formations in 14 samples confirmed by EDS analysis. In cultures, all serum samples and 13 tissue homogenates grew CNP. In ELISA, 14 samples were positive for CNP-antigen and 11 samples were positive for CNP-antibody.

Conclusion: There was evidence of a link between detection of CNP and presence of RP. Although causality was not demonstrated, these results suggest that further studies with negative control samples should be made to explore the etiology of RP formation, thus leading to a better understanding of the pathogenesis of stone formation.
