Developing effective tumor vaccines: basis, challenges and perspectives

XU Qingwen, CHEN Weifeng

《医学前沿（英文）》 2007年第1卷第1期页码 11-19 doi: 10.1007/s11684-007-0003-9

摘要： A remarkable advance in tumor immunology during the last decade is the elucidation of the antigenic basis of tumor recognition and destruction. A variety of tumor antigens have been identified using several strategies including conventional experiments and newly developed bioinformatics. Among these antigens, cancer/testis antigen (CT antigen) is considered to be the most promising target for immunotherapy by vaccination. Successful immunotherapy of tumors requires understanding of the natural relationship between the immune system and tumor in the status of differentiation, invasion and maturation. Continued progress in development of effective cancer vaccines depends on the identification of appropriate target antigens, the establishment of optimal immunization strategies without harmful autoimmune responses and the ability of manipulating tumor microenvironment to circumvent immune suppression and to augment the anti-tumor immune response.

Polymorphism of pharmaceutical molecules: perspectives on nucleation

Jie LU, Zhen LI, Xiaolin JIANG,

摘要： Polymorphism is a widespread phenomenon observed in more than half of all drug substances. Various polymorphs frequently possess different physical, chemical, mechanical and thermal properties that can profoundly affect the bioavailability, stability and other performance characteristics of the drug. Accordingly, the elucidation of the relationship between the particular polymorph of a pharmaceutical molecule and its functional properties is crucial to select the most suitable polymorph of the pharmaceutical molecule for development into a drug product. This review briefly introduces recent advances in the discovery and control of the polymorphs of pharmaceutical molecules, in terms of the enhancement of the selective nucleation of a particular polymorph. In the light of this, some cases discussed in the following is to be considered controversial.
