We present a very rare congenital immunologic disease, severe combined immunodeficiency syndrome (SCID) in 6-months-old-boy with prolonged mucocutaneous candidiasis, severe anaemia, skin rash similar to the infiltrative eczema of Langerhans cell histiocytosis (LCH) and subcutaneous nodules with histiocytic infiltration. Laboratory findings show profound absence of humoral and cell-mediated immu...

The severe combined immunodeficiency (SCID) mutation has been postulated to affect a V(D)J recombinase activity involved in coding joint formation. Analysis of 38 joints from 34 distinct sequences of normally rearranged T cell receptor (TCR) gamma and delta genes from adult, SCID thymocytes reveals coding joints with an increased number of P nucleotides. One-third of P sequences are greater tha...

Severe experimental infections with Cryptosporidium parvum have been reported in immunocompromised animals such as SCID mice (mice without functional T cells and B cells). In a C. parvum infection with 1 x 10(6) oocysts/mouse in SCID beige (SCIDbg) mice (SCID mice lacking functional NK cells), oocyst shedding was first demonstrated 18 days after infection. However, shedding was shown as early a...

Severe combined immunodeficiency (SCID) is a primary that presents with life-threating symptoms in early infancy and has poor prognosis if not promptly treated. Here we present an analysis of infectious presentation its course depending on clinical immunophenotypic form SCID. This study supported by the Independent Ethics Committee approved Academic Council Dmitry Rogachev National Medical Rese...

Saliva contains a wide variety of secretory proteins, including alpha-amylase, lysozyme, peroxidase, immunoglobulins, and mucins. Hyposecretion of saliva and consequent dry mouth will lead to severe dental caries, periodontal disease, and mucosal infections, resulting in degrade of quality of life. Polyposia development is one of sign usually seen in dry mouth patients. However, little is repor...

Severe combined immunodeficiency (SCID) is a life-threatening condition of newborns and infants caused by defects in genes involved in T cell development. Newborn screening (NBS) for SCID using the T cell receptor excision circle (TREC) assay began in Wisconsin in 2008 and has been adopted or is being implemented by all states in 2017. It has been established that NBS using the TREC assay is ex...

The severe combined immunodeficiency (scid) mouse has a defective V(D)J recombinase activity that results in arrested lymphoid development at the pro-B cell stage in the B lineage. The defect is not absolute and scid mice do attempt gene rearrangement. Indeed, approximately 15% of all scid mice develop detectable levels of oligoclonal serum immunoglobulin and T cell activity. To gain more insig...

We have attempted to model human metastatic disease by implanting human target organs into the immunodeficient C.B-17 scid/scid (severe combined immunodeficiency; SCID) mouse, creating SCID-hu mice. Preferential metastasis to implants of human fetal lung and human fetal bone marrow occurred after i.v. injection of human small cell lung cancer (SCLC) cells into SCID-hu mice; the homologous mouse...
