The CD8+ T cell diaspora has been analyzed after secondary challenge with an influenza A virus that replicates only in the respiratory tract. Numbers of DbNP366- and DbPA224-specific CD8+ T cells were measured by tetramer staining at the end of the recall response, then followed sequentially in the lung, lymph nodes, spleen, blood, and other organs. The extent of clonal expansion did not reflect the sizes of the preexisting memory T cell pools. Although the high-frequency CD8+ tetramer+ populations in the pneumonic lung and mediastinal lymph nodes fell rapidly from peak values, the “whole mouse” virus-specific CD8+ T cell counts decreased only 2-fold over the 4 weeks after infection, then subsided at a fairly steady rate to reach a plateau at about 2 months. The largest numbers were found throughout in the spleen, then the bone marrow. The CD8+DbNP366+ and CD8+DbPA224+ sets remained significantly enlarged for at least 4 months, declining at equivalent rates while retaining the nucleoprotein > acid polymerase immunodominance hierarchy characteristic of the earlier antigen-driven phase. Lowest levels of the CD69 “activation marker” were detected consistently on virus-specific CD8+ T cells in the blood, then the spleen. Those in the bone marrow and liver were intermediate, and CD69hi T cells were very prominent in the regional lymph nodes and the nasal-associated lymphoid tissue. Any population of “resting” CD8+ memory T cells is thus phenotypically heterogeneous, widely dispersed, and subject to broad homeostatic and local environmental effects irrespective of epitope specificity or magnitude.

The establishment of the Basque diaspora in Latin America can be divided in several different periods. First, from the 16th to 18th century, the so-called original diaspora of Basques who were part of the Spanish colonial regime. The second can be traced to the 19th century, consisting of a mixture of impoverished Basque migrants seeking jobs, especially in Uruguay and Argentina, and of refugees fleeing from the Spanish War of Independence and the Carlist wars. The third wave is identified by, but not only through, the considerable amount of refugees from the Spanish Civil War on the 1930's. The fourth wave came during the 1970s, with refugees from the Franco Dictatorship, ETA members and sympathisers. In this paper I will argue that each new wave of migrants brought tension to the diaspora, with the Euskal Etxeak, or ‘Basque houses’, as a focus point. The main idea is to analyse the different tensions and political discussions of this set of diasporic waves in Latin America.
