| Catalogue Number | 154101 |
| Parental Line | B cells from CD40 deficient patient |
| Synonyms | Tumour Necrosis Factor Receptor Super family Member 5, CD40L Receptor, B Cell Surface Antigen CD40, TNFRSF5 |
| Host | Human |
| Disease Keywords | Hyper IgM Syndrome type 3 |
| Model | Immortalised Line |
| Relevance | Hyper IgM syndromes is a group of primary immune deficiency disorders characterised by defective CD40 signalling; via B cells affecting class switch recombination (CSR) and somatic hyper mutation. Immunoglobulin (Ig) class switch recombination deficiencies are characterised by elevated serum Immunoglobulin M (IgM) levels and a considerable deficiency in Immunoglobulins G (IgG), A (IgA) and E (IgE). As a consequence, people with HIGM have decreased concentrations of serum IgG and IgA and normal or elevated IgM, leading to increased susceptibility to infections. Hyper IgM Syndrome type 3 is characterised by mutations of the CD40 gene. In this type, B cells cannot receive the signal from T cells to switch classes |
| Production Details | B Cells were isolated from PBMCs of CD40 deficient Hyper IgM Syndrome patients using standards methods. B cells were transformed with Epstein-Barr virus. |
| Conditional | No |
