  2. Tumor-infiltrating lymphocytes - Wikipedia

    en.wikipedia.org/wiki/Tumor-infiltrating_lymphocytes

    The cells are activated and grown prior to transfusion into the recipient (tumor bearer). In Adoptive T cell transfer therapy, TILs are expanded ex vivo from surgically resected tumors that have been cut into small fragments or from single cell suspensions isolated from the tumor fragments. Multiple individual cultures are established, grown ...

  3. Adoptive cell transfer - Wikipedia

    en.wikipedia.org/wiki/Adoptive_cell_transfer

    CD8 + T cells can exist in a stem cell–like state, capable of clonal proliferation. Human T memory stem cells express a gene program that enables them to proliferate extensively and differentiate into other T cell populations. [3] CD4 + T cells can also promote tumor rejection. CD4 + T cells enhance CD8 + T cell function and can directly ...

  4. Lymphoma in animals - Wikipedia

    en.wikipedia.org/wiki/Lymphoma_in_animals

    In most cases, appropriate treatment protocols cause few side effects, but white blood cell counts must be monitored. Allogeneic and autologous stem cell transplantations (as is commonly done in humans) have recently been shown to be a possible treatment option for dogs. [19] Most of the basic research on transplantation biology was generated ...

  5. T-cell depletion - Wikipedia

    en.wikipedia.org/wiki/T-cell_depletion

    Antiretroviral therapy, the most common treatment for patients with HIV, has been shown to restore CD4+ T cell counts. [20] The body responds to T cell depletion by producing an equal amount of T cells. However, over time, an individual's immune system can no longer continue to replace CD4+ T cells. [21] This is called the "tap and drain ...

  6. T memory stem cell - Wikipedia

    en.wikipedia.org/wiki/T_memory_stem_cell

    Longitudinal studies on T SCM dynamics in patients undergoing hematopoietic stem cell transplantation (HSCT) have shown that donor-derived T SCM cells were highly enriched early after HSCT, differentiated directly from Tn, and that Tn and T SCM cells (but not central memory or effector T cells) were able to reconstitute the entire heterogeneity of memory T cell subsets including T SCM cells. [6]

  7. Cellular adoptive immunotherapy - Wikipedia

    en.wikipedia.org/wiki/Cellular_adoptive...

    Immune cells such as T-cells are usually isolated from patients for expansion or engineering purposes and reinfused back into patients to fight diseases using their own immune system. A major application of cellular adoptive therapy is cancer treatment, as the immune system plays a vital role in the development and growth of cancer. [ 1 ]

  8. Histiocytoma (dog) - Wikipedia

    en.wikipedia.org/wiki/Histiocytoma_(dog)

    Canine histiocytoma cytology. A histiocytoma originates from epidermal Langerhans cells of antigen-presenting cell lineage. [4] Spontaneous regression is common in these tumors, and it is mediated by infiltration of CD8-expressing T cells followed by expression of Type 1 T helper cell cytokines (such as Interferon-gamma) and recruitment of antitumour effector cells.

  9. Priming (immunology) - Wikipedia

    en.wikipedia.org/wiki/Priming_(immunology)

    Subsequently, the primed cells will differentiate either into effector cells or into memory cells that can mount stronger and faster response to second and upcoming immune challenges. [2] T and B cell priming occurs in the secondary lymphoid organs (lymph nodes and spleen). Priming of naïve T cells requires dendritic cell antigen presentation.
