Contributor Information
- Name Pranab K Das
Tool Details
- Tool name: Immortalised CD40 deficient B Cell Line
- Alternate names: Tumour Necrosis Factor Receptor Super family Member 5, CD4L Receptor, B Cell Surface Antigen CD4, TNFRSF5
- Tool type: Cell Lines
- Parental cell line: B cells from CD40 deficient patient
- Organism: Human
- Disease: Hyper IgM Syndrome type 3
- Growth properties: Maintain at 3x105 to 7x105 cells per ml for optimal growth. Replenish growth medium twice per week
- Model: Immortalised Line
- Conditional: No
- Description: Can be used as antigen presenting cells. Hyper IgM syndromesÄÂ? is a group ofÄÂ? primary immune deficiency disordersÄÂ? characterised by defectiveÄÂ? CD40ÄÂ? signalling;ÄÂ? viaÄÂ? B cellsÄÂ? affectingÄÂ? class switch recombinationÄÂ? (CSR) andÄÂ? somatic hyper mutation.ÄÂ? ImmunoglobulinÄÂ? (Ig) class switch recombination deficiencies are characterised by elevated serumÄÂ? Immunoglobulin MÄÂ? (IgM) levels and a considerable deficiency inÄÂ? Immunoglobulins GÄÂ? (IgG),ÄÂ? AÄÂ? (IgA) andÄÂ? EÄÂ? (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
- Research area: Cell biology; Immunology
- 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.
