Lymphome
Un lymphome, aussi plus rigoureusement appelé lymphome malin ou lymphosarcome, est un cancer du système lymphatique qui se développe aux dépens des lymphocytes. Il est caractérisé par des proliférations cellulaires malignes (ou cancers) ayant pris naissance dans un organe lymphoïde secondaire : nœuds lymphatiques, rate ou tissus lymphoïdes associés aux muqueuses (digestives et respiratoires notamment). Les lymphomes, comme les leucémies, font partie des hémopathies malignes.
Programmed cell death
Programmed cell death (PCD; sometimes referred to as cellular suicide) is the death of a cell as a result of events inside of a cell, such as apoptosis or autophagy. PCD is carried out in a biological process, which usually confers advantage during an organism's lifecycle. For example, the differentiation of fingers and toes in a developing human embryo occurs because cells between the fingers apoptose; the result is that the digits are separate. PCD serves fundamental functions during both plant and animal tissue development.
