The Role of the Spleen in Ischemic Stroke

Abstract: This opinion piece highlights the scientific literature reporting that the peripheral immune response to ischemic stroke originates from the spleen. Removal of the spleen not only reduces stroke-induced neurodegeneration but also cellular degeneration in the body's other tissues when exposed to ischemic conditions.

“…3,32,33 A strong correlation between post-stroke activation of the immune system and changes in spleen have been described in animal models. 4 These include a reduction in number and apoptotic cell death of splenocytes, changes in cellularity and phenotype of splenocytes, and splenic atrophy. 6,[10][11][12][13][14]16,25 The translation of these findings in stroke patients remain challenging, and require a careful estimation of pre-stroke spleen volume as well as other contributory and confounding clinical factors.…”

“…Наряду с костным мозгом источником лейко-цитов на периферии является селезенка, сокра-щение которой сопровождается высвобождением спленоцитов в циркуляцию и их миграцией в зону первичного ишемического поражения [110], что опосредует иммунные механизмы вторичных по-вреждений [91]. У человека активация селезенки проявляется сокращением ее размеров и выявля-ется у 40% пациентов.…”

“…In parallel to events within the brain, lymphocytes, neutrophils, and monocytes traffic to the brain from the periphery and contribute to further neuronal damage. The spleen is a principal reservoir that reduces in size after stroke, releasing inflammatory cells and cytokines into the circulation [8][9][10][11][12][13][14][15]. In addition, the bone marrow mobilizes a subpopulation of multipotent stem cells into the peripheral blood following stroke, which is then directed towards the brain, as well as peripheral organs such as the spleen [16].…”
