Protective Immunity to Amebiasis: New Insights and New Challenges

New insights on the development of fungal vaccines: from immunity to recent challenges

Fungal infections are emerging as a major problem in part due to high mortality associated with systemic infections, especially in the case of immunocompromised patients. With the development of new treatments for diseases such as cancer and the acquired immune deficiency syndrome pandemic, the number of immunosuppressed patients has increased and, as a consequence, also the number of invasive ...

Imprinting meets genomics: new insights and new challenges.

Until recently, only a handful of imprinted genes, or genes with parent-of-origin dependent expression patterns, were known in plants. Study of these genes yielded key insights into mechanisms of monoallelic expression and imprinted gene function. The recent application of high throughput sequencing to the study of imprinting has confirmed that many previous findings are relevant on a genome-wi...

Cryptosporidium species: new insights and old challenges.

Cryptosporidium species are protozoan parasites that cause mainly enteric illnesses in humans and other animals. The mode of transmission is most commonly waterborne, but other sources of infection, including foodborne and person-to-person spread, have been documented. The environmental form of the parasite is resistant to most water purification methods, including chlorination. Cryptosporidium...

New insights into upper airway innate immunity

BACKGROUND Protecting the upper airway from microbial infection is an important function of the immune system. Proper detection of these pathogens is paramount for sinonasal epithelial cells to be able to prepare a defensive response. Toll-like receptors and, more recently, bitter taste receptors and sweet taste receptors have been implicated as sensors able to detect the presence of these path...
