Haemic and immune systems

The haemic and immune systems are the systems of organs and tissues, including the bone marrow, spleen, thymus and lymph nodes, involved in the production of cellular blood components.

    Exhausted cytotoxic T lymphocytes (CTLs) express the receptor PD-1 as a key signature. Haining and colleagues show that there are different ‘depths’ of exhaustion with a subset of exhausted CTLs that retain polyfunctionality and are responsive to PD-1 blockade.

    The immune checkpoint molecule PD-1 is expressed on a fraction of CD4+ T cells latently infected with HIV, but whether PD-1 plays a functional role in reservoir persistence remains unknown. Here, Fromentin et al. show that PD-1 blockade potentiates latency reversal ex vivo in CD4+ T cells from ART suppressed individuals.

    Stemness is crucial for the maintenance of long-term T cell memory. Gattinoni and colleagues demonstrate that the transcription factor c-Myb is essential for the establishment of a stemness program in the CD8+ T cell memory compartment.

    Double-strand breaks in DNA generated during the normal assembly and diversification of lymphocyte antigen receptor genes or by genotoxic agents during infection activate DNA damage responses. Besides repairing damaged DNA, these responses trigger important signalling events that regulate immune cell development and function.
