  2. Bamlanivimab - Wikipedia

    en.wikipedia.org/wiki/Bamlanivimab

    Bamlanivimab is an IgG1 monoclonal antibody (mAb) directed against the spike protein of SARS-CoV-2. [13] The aim is to block viral attachment and entry into human cells, thus neutralizing the virus, and help preventing and treating COVID-19. [8]

  3. Naive B cell - Wikipedia

    en.wikipedia.org/wiki/Naive_B_cell

    In immunology, a naive B cell is a B cell that has not been exposed to an antigen. These are located in the tonsils , spleen , and primary lymphoid follicles in lymph nodes . Once exposed to an antigen , the naive B cell either becomes a memory B cell or a plasma cell that secretes antibodies specific to the antigen that was originally bound.

  4. B cell - Wikipedia

    en.wikipedia.org/wiki/B_cell

    B cells, also known as B lymphocytes, are a type of white blood cell of the lymphocyte subtype. [1] They function in the humoral immunity component of the adaptive immune system. [1] B cells produce antibody molecules which may be either secreted or inserted into the plasma membrane where they serve as a part of B-cell receptors. [2]

    en.wikipedia.org/wiki/Seroconversion

    Several studies have demonstrated that individuals who recovered from COVID-19 infections and are seropositive for COVID-19 at the time of vaccination produce significantly more anti-spike IgG antibodies in response to vaccination than individuals who are not seropositive for COVID-19, while individuals who have recovered from COVID-19 ...

    These B cells produce IgM antibodies to help clear infection. [20] T-bet memory B cells. T-bet B cells are a subset that have been found to express the transcription factor T-bet. T-bet is associated with class switching. T-bet B cells are also thought to be important in immune responses against intracellular bacterial and viral infections. [21]

  9. Lymphocyte - Wikipedia

    en.wikipedia.org/wiki/Lymphocyte

    A lymphocyte is a type of white blood cell (leukocyte) in the immune system of most vertebrates. [1] Lymphocytes include T cells (for cell-mediated and cytotoxic adaptive immunity), B cells (for humoral, antibody-driven adaptive immunity), [2] [3] and innate lymphoid cells (ILCs; "innate T cell-like" cells involved in mucosal immunity and homeostasis), of which natural killer cells are an ...
