Cells and Problems Flashcards
Expresses Foxp3 and CD25 and secretes IL-10. Deficient in the monogenic autoimmune disease known as IPEX (immune dysregulation, polyendocrinopathy, enteropathy, X-linked syndrome)
- Th17 cell
- Macrophage
- Epithelial cell
- T reg cell
- Dendritic cell
- CD4+ T cell
- Neutrophil
- Th1 cell
- Plasma cell
- Megakaryocyte
- Lymphocyte
T-reg cells
In the immature form these cells are adapted for recognition and uptake of pathogens. Maturation is associated with expression of CCR7, migration to lymph nodes and enhanced capacity for antigen presentation.

- Dendritic cell
- CD4+ T cell
- Neutrophil
- Th1 cell
- Plasma cell
- Megakaryocyte
- Lymphocyte
Dendritic cells
These cells can be rapidly mobilised from bone marrow. They express pathogen recognition receptors and Fc receptors and are able to engage in oxidative and non-oxidative killing. They do not express HLA class II molecules and so do not activate CD4 T cells. They are the predominant cell type in synovial fluid taken from patients with gout,

- CD4+ T cell
- Neutrophil
- Th1 cell
- Plasma cell
- Megakaryocyte

Neutrophils
These cells may be formed following a germinal centre reaction involving isotype switching and affinity maturation of receptors. They are long-lived and reside in bone marrow.

Plasma cells
These cells express CD3 and secrete IL-17 and IL-22. They are thought to be important in some auto-immune conditions including rheumatoid arthritis.

Th17 cells
These cells may be resident in peripheral tissues (eg Kupffer cells in liver, microglia in neural tissue) express pathogen recognition receptors and Fc receptors and are able to engage in oxidative and non-oxidative killing. They are an important source of cytokines such as IL-1 and TNF-alpha and are thought to play an important role in some auto-inflammatory and auto-immune diseases.

Macrophages
The normal function of these cells is to express cytokines in response to recognition of specific peptides presented by HLA class II molecules. Depletion of these cells during HIV infection is an important factor in development of AIDS.
