Phagocytic cells and Streptococcus pyogenes in invasive infections : an inflammatory relationship
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2017-12-21)Severe Streptococcus pyogenes infections, such as streptococcal toxic shock syndrome and necrotizing soft tissue infections, are rare but life threatening conditions. They are characterized by high bacterial load and a ... -
Innate lymphoid cell heterogeneity in human tissues at steady state and during inflammation
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2017-11-23)The family of innate lymphoid cells (ILCs) is the most recently identified group of innate immune cells. The ILC classification groups the cells according to their transcription factor and cytokine profile into ILC1, ILC2 ... -
The role of monocytes in chronic inflammatory diseases
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2017-11-15)Monocytes and monocyte-derived cells are important players in the orchestration of inflammatory reactions in blood and peripheral tissues. However, little is known about the monocyte fate upon entry into human tissues, and ... -
Role of MAIT cells in human antimicrobial immunity
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2017-10-31)Mucosa-associated invariant T (MAIT) cells are a relatively recently discovered subset of unconventional T cells. In humans, MAIT cells are predominantly CD8+CD4- (CD8+) with a smaller CD8-CD4- (double-negative, DN) subset, ... -
Human cytotoxic lymphocyte differentiation in health and disease
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2017-10-26)Cytotoxic lymphocytes, comprising natural killer (NK) cells and CD8+ cytotoxic T cells, eradicate infected or malignant cells by release of lytic granules and alarm the immune system through production of pro-inflammatory ... -
Understanding chronic immunodeficiency disorders through assessment of cytotoxic lymphocyte function
(Inst för medicin, Huddinge / Dept of Medicine, Huddinge, 2017-09-20)Representing an evolving and diverse group of syndromes, immunodeficiencies can currently be viewed as a spectrum of disorders where a dysfunction of the immune system plays a significant etiologic role. Cytotoxic lymphocytes ... -
