  1. The results appear contradictory. If the CD5-high population produces more IL-2, it should be less, not more, dependent on exogenous IL-2 for Foxp3+ Treg conversion.

  3. #Sangamo had one of the most advanced CAR-Treg programs in the field, the HLA-A2–directed TX200 (STEADFAST) kidney transplant tolerance program.

    Is it going to be discontinued?

  5. These results are difficult to explain. How can a malaria-primed memory T-cell pool depleted of Tregs be less effective upon recall than either the same pool containing Tregs or even purified memory Tregs alone?

  13. Why do Tregs accumulate within tumors? What antigen do they recognize, is it a self antigen, a neoantigen, or a cryptic antigen? Without determining the antigen specificity of these Tregs, we are basically going in circles without advancing.

    1. Unlike the innate immune system, which uses receptors to discriminate self from nonself based on biochemical features of the ligand (like LPS, foreign DNA, or foreign RNA)

  27. 6/ How can antigen-specific Tregs lose their functionality? By losing the antigen. Without the anchor antigen to engage the Treg TCR and collaborate with other T cells for IL-2, the process breaks down. 🔓

    #AntigenSpecific

  28. 9/ If the lost anchor antigen is similar to the target self-antigen, Treg–IL-2+ T cell collaboration stays intact. 🔄 If they’re different, losing the anchor antigen shouldn’t affect other self-antigens. ⚖️ No disruption → No autoimmunity!

  29. 7/ But how could we lose a self-antigen? Not realistic. And if a self-antigen is lost, how can autoimmunity occur? No antigen, no autoimmunity. 🚫

  32. 4/ Based on this evidence, if Tregs inhibit other T cells in an antigen-specific manner, they must recognize similar antigens. Likewise, IL-2 supply from other T cells is also likely antigen-specific. 🔑

  44. 'We have previously demonstrated that excising transcription factor Kruppel-like factor 2 (Klf2) within the T cell lineage blocks the generation of peripheral-derived Tregs (pTregs) without impairing production of thymic-derived Tregs. Using this mouse model, we have now demonstrated that eliminating pTregs is sufficient to delay/prevent tumor malignancy without causing autoimmunity.'

  46. “It’s difficult to think of a disease, injury or injection that doesn’t involve some kind of #immune #response,
    and our finding really changes the way we could control this response,” said Professor Adrian Liston from the University’s Department of Pathology and the study’s corresponding author.

    “We’ve uncovered new rules of the immune system.
    This ‘unified healer army’ can do everything
    – repair injured muscle, make your fat cells respond better to insulin, regrow hair follicles.

    To think that we could use it in such an enormous range of diseases is fantastic:
    it’s got the potential to be used for almost everything.”

    Lymphoid organs are integral parts of the immune system, responsible for producing #lymphocytes, a type of white blood cell that includes T cells.

    T cells begin life in the bone marrow and then move to the thymus, an organ in the upper mid-chest,
    where they mature into specialized subsets, including #Tregs.

    Once fully matured, T cells are exported to peripheral lymphatic tissues and organs like the spleen, tonsils, and lymph nodes
    (some move to the bloodstream).

    It was thought that’s where Tregs stayed, on ‘standby’ until called upon by the immune system.

    To test this, the researchers analyzed the Tregs present in 48 different tissues in mice, including lymphoid and non-lymphoid tissues and tissues associated with the gut.

    They found them in all tissue types, suggesting that Tregs weren’t specialized cell populations confined to lymphoid tissues but moved around the body, executing repair functions in areas that need it.

    “Now that we know these regulatory T cells are present everywhere in the body, in principle ⭐️we can start to make immune suppression and tissue regeneration treatments that are targeted against a single organ⭐️
    – a vast improvement on current treatments that are like hitting the body with a sledgehammer,” Liston said
