Long-lasting immunity by early infection of maternal-antibody-protected infants


Navarini, A A; Krzyzowska, M; Lang, K S; Horvath, E; Hengartner, H; Niemialtowski, M G; Zinkernagel, R M (2010). Long-lasting immunity by early infection of maternal-antibody-protected infants. European Journal of Immunology, 40(1):113-116.

Abstract

Newborn higher vertebrates are largely immuno-incompetent and generally survive infections--including poxviruses--by maternal antibody protection. Here, we show that mice survived epidemics as adults only if exposed to lethal orthopoxvirus infections during infancy under the umbrella of maternal protective antibodies. This implies that both the absence of exposure to infection during early infancy or of effective vaccination renders the population highly susceptible to new or old re-emerging pathogens.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
