Pichia Pastoris (Komagataella Phaffii) As a Cost-Effective Tool for Vaccine
bioengineering Review Pichia pastoris (Komagataella phaffii) as a Cost-Effective Tool for Vaccine Production for Low- and Middle-Income Countries (LMICs) Salomé de Sá Magalhães and Eli Keshavarz-Moore * Department of Biochemical Engineering, University College London, Gower Street, London WC1E 6BT, UK; [email protected] * Correspondence: [email protected] Abstract: Vaccination is of paramount importance to global health. With the advent of the more recent pandemics, the urgency to expand the range has become even more evident. However, the potential limited availability and affordability of vaccines to resource low- and middle-income countries has created a need for solutions that will ensure cost-effective vaccine production methods for these countries. Pichia pastoris (P. pastoris) (also known as Komagataella phaffii) is one of the most promising candidates for expression of heterologous proteins in vaccines development. It combines the speed and ease of highly efficient prokaryotic platforms with some key capabilities of mammalian systems, potentially reducing manufacturing costs. This review will examine the latest developments in P. pastoris from cell engineering and design to industrial production systems with focus on vaccine development and with reference to specific key case studies.

Received: 13 August 2012; in revised form 30 August 2012 / Accepted: 30 August 2012 / Published: 13 September 2012 Abstract: Health research programs targeting the population of Gabon and Equatorial Africa at the International Center for Medical Research in Franceville (CIRMF), Gabon, have evolved during the years since its inception in 1979 in accordance with emerging diseases. Since the reemergence of Ebola virus in Central Africa, the CIRMF “Emerging Viral Disease Unit” developed diagnostic tools and epidemiologic strategies and transfers of such technology to support the response of the National Public Health System and the World Health Organization to epidemics of Ebola virus disease. The Unit carries out a unique investigation program on the natural history of the filoviruses, emergence of epidemics, and Ebola virus pathogenesis. In addition, academic training is provided at all levels to regional and international students covering emerging conditions (host factors, molecular biology, genetics) that favor the spread of viral diseases. -

The 1947 legislation has served us well. It has undergirded our diplomatic efforts, provided the basis to establish our military capa- bilities, and focused our intelligence assets. But the world has changed dramatically in the last fifty years, and particularly in the last decade. Institutions designed in another age may or may not be appropriate for the future. It is the mandate of the United States Commission on National Security/21st Century to examine precise- ly that question. It has undertaken to do so in three phases: the first to describe the world emerging in the first quarter of the next century, the second to design a national security strategy appropri- ate to that world, and the third to propose necessary changes to the national security structure in order to implement that strategy effectively. -

It is a major socioeconomic and public health concern. It is estimated that 600 million people are chronically infected, with up to135,000 deaths annually [2]. Most infections occur in the Asian region (60-70million people in each), followed by Nigeria and the Democratic Republic of Congo in Africa and Brazil (30-40 million people in each) [3]. The economic burden of chronic hookworm infection is estimated at 4.5 million DALYs annually [4] and is among the most important neglected tropical disease [5]. Southeast Asia (SEA) has a large percentage of populations living in rural and remote areas where hookworm infection is common [6]. These areas generally have poor sanitation and access to untreated water, which increase the opportunity of hookworm transmission and infection. Hookworm infection has been associated with impaired learning and decrease in productivity [7]. -

FOREIGNPOLICYANALYSIS Jakarta's Juggling Act: Balancing China and America in the Asia-Pacific Jessica Brown EXECUTIVE SUMMARY No. 5 • 3 February 2011 Indonesia, long thought of as a basket case, has emerged as one of the key players in the Asia-Pacific. Its democracy, while young and still consolidating, has proved to be remarkably resilient. While other countries are undergoing painful recessions, thanks to the global financial crisis, Indonesia is experiencing sustained economic growth. It has emerged as a key regional player on the diplomatic stage, forging strong bilateral relationships with its neighbours and joining the influential G20 group of major economies. The archipelagic nation is also strategically significant. Straddling the Indian and Pacific oceans, it abuts the busy Malacca Strait—through which half of the world’s commercial tonnage sails—and the contested South China Sea. Any serious assessment of Southeast Asia’s security outlook must now include Indonesia. Indonesia’s overriding security concern is the rise of China. Like most of its neighbours, Indonesia sees both opportunities and threats in this emerging giant. Indonesia, which is rich in natural resources and in desperate need of foreign investment to update its inadequate infrastructure, knows that its economic development is tied to China’s growth. But while Indonesia wants to piggyback on China’s economic ascent, it does not want China to dominate the region politically. Instead, Indonesia would prefer to preserve the status quo. Its colonial history has made it wary of being dominated by great powers. However, it believes that the existing US-led security order is the best way to ensure China does not become the predominant security actor in the region.
