Recent progress includes the identification of gain-of-function mutations in STAT1 as a cause of an IPEX-like disease, emerging FOXP3 genotype/phenotype relationships in IPEX, and the elucidation of a role for the microbiota in the immune dysregulation associated with regulatory T cell deficiency.
He was found to have T-cell deficiency with lack of red and white cell purine nucleoside phosphorylase enzyme activity.A spastic tetraparesis was noted.
Although decreased mast cells correlated with higher parasite egg burden and delayed clearance in vivo, T cell deficiency in IL-9 also likely contributes to the phenotype.
Manipulation of the ILC-IL-22-TEC axis may be useful for augmenting immune reconstitution after clinical hematopoietic transplantation and other settings of T-cell deficiency.
Ozone increased ST2+ γδ T cells, indicating that these cells can be targets of IL-33, and γδ T cell deficiency reduced obesity-related increases in the response to ozone, including increases in type 2 cytokines.

We found that 2 young adult siblings presenting with T cell deficiency and various infectious diseases, including persistent EV-HPV infections, were homozygous for a mutation creating a stop codon in the ras homolog gene family member H (RHOH) gene.
Taken together, the novel CD8(+) Gp120-Texo vaccine capable of stimulating efficient CD4(+) T cell-independent Gp120-specific CD8(+) CTL responses leading to therapeutic and long-term immunity in Tg HLA-A2 mice may represent a new immunotherapeutic vaccine for treatment of HIV-1 patients with CD4(+) T cell deficiency.
Moreover, the gene transfer procedure partly rescued the NK and memory T-cell deficiency observed in IL-15Rα(-/-) mice. pApo-hIL15+ pSushi gene transfer to the liver showed a modest therapeutic activity against subcutaneously transplanted MC38 colon carcinoma tumors, that was more evident when tumors were set up as liver metastases.
Based on the previous discovery of STIM1 deficiency in a single family with a severe T cell immunodeficiency and the much higher risk of KS in individuals with acquired T cell deficiencies, we conclude that STIM1T cell deficiency precipitated the development of lethal KS in this child upon infection with HHV-8.
Thus, cytokine receptor deficiencies may contribute to immune deficiency in HIV-infected patients, and Cgamma chain cytokines may play an important role in vivo in immune homeostasis in lymphopenic patients by maintaining the memory subsets of T cells in patients with CD4 T cell deficiency.

Artemis gene mutations are responsible for the development of a severe combined immunodeficiency [radiation-sensitive (RS) SCID] characterized by a severe B and T cell deficiency and a normal natural killer cell population.
Patients with a moderate X-linked combined immunodeficiency (XCID) owing to a single missense mutation in the common gamma chain (gammac) gene (L-->Q271) were found to have a progressive T-cell deficiency.
Furthermore, injection of normal bone marrow cells into the T-cell deficient mice led to the generation of mature T cells indicating that the T-cell deficiency was caused by the action of HSP70 in T cells.
CATCH 22 is an acronym for cardiac defect, abnormal facies, thymic hypoplasia or aplasia and T-cell deficiency, cleft palate, hypoparathyroidism, and hypocalcemia.
