Immune dysregulation, including neuroinflammation, brain autoantibodies, and altered adaptive responses, has been implicated in autism pathophysiology. To address these immune alterations, autologous cord blood transfusion has been proposed as a therapy, given its abundance of immune regulatory cells and lack of rejection risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Using multi-parametric mass cytometry, we profiled the peripheral blood mononuclear cells from children with autism at pre-transfusion and 6 months post-transfusion to assess the effects of this intervention on effector and regulatory subsets.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Our results showed that transfusion did not increase regulatory T or B cells.
