Evidence of ALA on adaptive immune cells.

T cellB cell

Animal modelEAEDecrease the number of Th17 and Th1 in CNS;
Increase Treg numbers in spleen;
Reduce migration.
High fat diet miceRecover transcriptional levels of the differentiation-related genes of jejunal T cells.Restore transcriptional levels of BCR signaling pathway relating genes;
Decrease the apoptotic percentage of splenic B lymphocytes.
Atopic dermatitisSuppress production of IFN-γ and IL-4 by CD4+T.Reduce total serum IgE levels.
Models of established atherosclerosisReduce T cell migration in response to chemokines.
Endotoxemia miceIncrease the number of splenic B cells.

PatientsAIDSIncrease the number of Th cells;
Improve the lymphocyte proliferation response;
Ameliorate the impaired mitochondrial function of CD4+T cells.
Advanced cancerInduce lymphocyte progression from G0/G1 to S phase.
Jurkat T cellsInhibit NF-κB activation induced by TNF
Reduce migration.

Normal humanIncrease cAMP which affects proliferation and activation of T cells;
Down-regulate the expression of CD4 molecules;
Reduce migration.
