Congenital Disorders of Lymphocyte Function
SCID can be diagnosed at birth by measuring levels of TCR excision circles (TRECs). TRECs are a byproduct of V(D)J recombination and are present as circularized DNA fragments in newly generated, naive T lymphocytes that express the αβ form of the TCR.
Simply so, What is TREC Holder?
KARACHI: The apex regulator Securities and Exchange Commission of Pakistan (SECP) has advised stock exchanges to ensure that all Trading Right Entitlement Certificate (TREC) holders (card holders prior to demutualisation) get themselves registered as ‘brokers’ with the SECP by Aug 26, 2014.

Can IgE class switch to IgG?
Ig heavy chain class switching occurs rapidly after activation of mature naïve B cells, resulting in a switch from expressing IgM and IgD to expression of IgG, IgE, or IgA; this switch improves the ability of antibodies to remove the pathogen that induces the humoral immune response.
Can IgE switch to IgG?
If these activated B cells encounter specific signaling molecules via their CD40 and cytokine receptors (both modulated by T helper cells), they undergo antibody class switching to produce IgG, IgA or IgE antibodies (from IgM or IgD) that have defined roles in the immune system.

What are the two main functions of B cells?
The main functions of B cells are:
- to make antibodies against antigens,
- to perform the role of antigen-presenting cells (APCs),
- to develop into memory B cells after activation by antigen interaction.
