Linfocito que se desarrolla en la médula ósea representando una pequeña porción de la población de linfocitos y carece de los marcadores de superficie de los linfocitos B y T. Estimulada por la presencia de un antígeno, la célula nula ataca directamente, sin que tenga que mediar otro mecanismo, por lo que se les llama asesinas naturales.  1, record 1, Spanish, - c%C3%A9lula%20nula

Elle constitue 60 à 70 % des lymphocytes périphériques et est également présente dans les zones paracorticales des ganglions lymphatiques ainsi que dans les manchons périartériolaires de la rate. Lorsqu’il rencontre un antigène, le lymphocyte T le détruit, soit directement par cytotoxicité, soit indirectement par activation des lymphocytes B ou des macrophages : c’est l’immunité à médiation cellulaire.  2, record 2, French, - lymphocyte%20T

An encounter with a foreign pathogen or antigen stimulates naive T lymphocyte activation and the generation of immunologic memory. The T cells which are responsible for immunologic memory differ, both phenotypically and functionally, from naive T cells. Of interest is the observation that aging is associated with an enhanced level of memory T cells, suggesting that the qualitative T cell response differs in the elderly. Further, differences in the proportion of memory to naive T cells may be responsible for immune dysfunction and autoimmunity associated with the aging process. In general, the goal of our research is to characterize the differences between antigenically naive (virgin) and memory T helper cells at the developmental, phenotypic, and functional levels  1, record 5, English, - naive%20T%20lymphocyte
