Abstract
CD4+ T cells are vital for host defense and immune regulation. However, the fundamental role of CD4 itself remains enigmatic. We report seven patients aged 5-61 years from five families of four ancestries with autosomal recessive CD4 deficiency and a range of infections, including recalcitrant warts and Whipple's disease. All patients are homozygous for rare deleterious CD4 variants impacting expression of the canonical CD4 isoform. A shorter expressed isoform that interacts with LCK, but not HLA class II, is affected by only one variant. All patients lack CD4+ T cells and have increased numbers of TCRαβ+CD4-CD8- T cells, which phenotypically and transcriptionally resemble conventional Th cells. Finally, patient CD4-CD8- αβ T cells exhibit intact responses to HLA class II-restricted antigens and promote B cell differentiation in vitro. Thus, compensatory development of Th cells enables patients with inherited CD4 deficiency to acquire effective cellular and humoral immunity against an unexpectedly large range of pathogens. Nevertheless, CD4 is indispensable for protective immunity against at least human papillomaviruses and Trophyrema whipplei.

Abstract
Monoclonal antibodies (mAbs) that recognize cluster of differentiation (CD) molecules on lymphocytes are useful tools for the study of different lymphocyte subsets in flow cytometry (FCM) analysis. CD4 is a glycoprotein found on the surfaces of helper T cells, monocytes, macrophages, and dendritic cells. In this study, we describe Japanese Black (JB) calves in a farm whose peripheral blood mononuclear cells (PBMCs) did not react with a CD4-specific mAb. To identify calves with PBMCs with low mAb reactivity, PBMCs from 21 JB calves (1-12 months of age) bred at the same farm were examined using two different bovine CD4 mAbs (clones #CC8 and #CACT138A). FCM analysis indicated that the calves fell into two groups based on reactivity against the two mAbs, i.e., double-positive (DP) calves, whose PBMCs were recognized by both mAbs clones, and single-positive (SP) calves, whose PBMCs were only recognized by #CACT138A. PBMCs from seven calves were not recognized by #CC8, although they had normal reactivity with another mAb, #CACT138A. Sequencing analysis of the CD4 gene in these calves revealed four nucleotide substitutions (G918 T, A930C, G970A, and G1074A) in the coding region in the SP group when compared to the DP group. Three of the four mutations were associated with amino acid substitution (Q306H, K310 N, and A324 T). The substitution at A324 T was located in the D4 domain of CD4 gene. Homology modeling based on the amino acid sequences revealed that the surface structure of this part of the molecule was significantly different between the SP and the DP groups. Therefore, the epitope recognized by the #CC8 CD4 mAb was altered in calves with this genetic mutation, and this led to the low reactivity of the PBMCs from calves in the SP group aginst the #CC8 mAb. In conclusion, this is the first study to identify CD4 variants in JB cattle. We confirmed that the variants did not affect lymphocyte functions, such as mitogen stimulation or lipopolysaccharide-induced cytokine gene expression.

Abstract
Innate lymphoid cell (ILC) lineages mirror those of CD4+ T helper cell subsets, producing type 1, 2 and 3 cytokines respectively. Studies in adult human populations have shown contributions of non-cytotoxic ILC to immune regulation or pathogenesis in a wide range of diseases and have prompted investigations of potential functional redundancy between ILC and T helper cell compartments in neonates and children. To investigate the potential for ILC to contribute to immune responses across the human lifespan, we examined the numbers and frequencies of peripheral blood ILC subsets in a cohort of Gambians aged between 5 and 73 years of age. ILC2 were the most abundant peripheral blood ILC subset in this Gambian cohort, while ILC1 were the rarest at all ages. Moreover, the frequency of ILC1s (as a proportion of all lymphocytes) was remarkably stable over the life course whereas ILC3 cell frequencies and absolute numbers declined steadily across the life course and ILC2 frequencies and absolute numbers declined from childhood until the age of approx. 30 years of age. Age-related reductions in ILC2 cell numbers appeared to be partially offset by increasing numbers of total and GATA3+ central memory (CD45RA-CCR7+) CD4+ T cells, although there was also a gradual decline in numbers of total and GATA3+ effector memory (CD45RA-CCR7-) CD4+ T cells. Despite reduced overall abundance of ILC2 cells, we observed a coincident increase in the proportion of CD117+ ILC2, indicating potential for age-related adaptation of these cells in childhood and early adulthood. While both CD117+ and CD117- ILC2 cells produced IL-13, these responses occurred predominantly within CD117- cells. Furthermore, comparison of ILC frequencies between aged-matched Gambian and UK young adults (25–29 years) revealed an overall higher proportion of ILC1 and ILC2, but not ILC3 in Gambians. Thus, these data indicate ongoing age-related changes in ILC2 cells throughout life, which retain the capacity to differentiate into potent type 2 cytokine producing cells, consistent with an ongoing role in immune modulation.

Complete Multilineage CD4 Expression Defect Associated With Warts Due to an Inherited Homozygous CD4 Gene Mutation. Front Immunol 2019; 10:2502.

Abstract
Idiopathic T-CD4 lymphocytopenia (ICL) is a rare and heterogeneous syndrome characterized by opportunistic infections due to reduced CD4 T-lymphocytes (<300 cells/μl or <20% T-cells) in the absence of HIV infection and other primary causes of lymphopenia. Molecular testing of ICL has revealed defects in genes not specific to CD4 T-cells, with pleiotropic effects on other cell types. Here we report for the first time an absolute CD4 lymphocytopenia (<0.01 CD4+ T-cells/μl) due to an autosomal recessive CD4 gene mutation that completely abrogates CD4 protein expression on the surface membrane of T-cells, monocytes, and dendritic cells. A 45-year-old female born to consanguineous parents consulted because of exuberant, relapsing, and treatment-refractory warts on her hands and feet since the age of 10 years, in the absence of other recurrent infections or symptoms. Serological studies were negative for severe infections, including HIV 1/2, HTLV-1, and syphilis, but positive for CMV and EBV. Blood analysis showed the absence of CD4+ T-cells (<0.01%) with repeatedly increased counts of B-cells, naïve CD8+ T-lymphocytes, and particularly, CD4/CD8 double-negative (DN) TCRαβ+ TCRγδ- T-cells (30% of T-cells; 400 cells/μl). Flow cytometric staining of CD4 using monoclonal antibodies directed against five different epitopes, located in two different domains of the protein, confirmed no cell surface membrane or intracytoplasmic expression of CD4 on T-cells, monocytes, and dendritic cells but normal soluble CD4 plasma levels. DN T-cells showed a phenotypic and functional profile similar to normal CD4+ T-cells as regards expression of maturation markers, T-helper and T-regulatory chemokine receptors, TCRvβ repertoire, and in vitro cytokine production against polyclonal and antigen-specific stimuli. Sequencing of the CD4 gene revealed a homozygous (splicing) mutation affecting the last bp on intron 7-8, leading to deletion of the juxtamembrane and intracellular domains of the protein and complete abrogation of CD4 expression on the cell membrane. These findings support previous studies in CD4 KO mice suggesting that surrogate DN helper and regulatory T-cells capable of supporting antigen-specific immune responses are produced in the absence of CD4 signaling and point out the need for better understanding the role of CD4 on thymic selection and the immune response.

Abstract
The cluster of differentiation 4 (CD4) molecule functions as a co-receptor for MHC class II binding to TCR in T helper cells. A CD4 epitope deficiency was identified in the swine MeLiM (melanoblastoma-bearing Libechov minipig) strain, a model for spontaneous cutaneous melanoma development and regression. Extensive sequencing revealed a high genetic variability of CD4 and the existence of several haplotypes segregating in MeLiM. Forty polymorphisms were identified in the coding sequence, out of which 20 correspond to non-synonymous variants and 10 are located in the 3'UTR of CD4 transcripts. One of the haplotypes segregating in the MeLiM explained the epitope deficiency observed. An association analysis between CD4 genotype and several phenotypes related to tumor regression was performed in 267 animals. An association was evidenced between a MeLiM alternative CD4 haplotype and skin and eye depigmentation, as well as the extent of hair depigmentation. Also, seric IgG concentration was shown to be higher in pigs carrying the alternative haplotype at the homozygous state. In conclusion, the genetic variability of the CD4 gene is associated with immune response-related phenotypes in MeLiM minipigs.

Abstract
Human immunodeficiency virus (HIV) is the chief contributor to global burden of disease. In 2010, HIV was the fifth leading cause of disability-adjusted life years in people of all ages and leading cause for people aged 30-44 years. It is classified as a member of the family Retroviridae and genus Lentivirus based on the biological, morphological, and genetic properties. It infects different cells of the immune system, such as CD4+ T cells (T-helper cells), dendritic cells, and macrophages. HIV has two subtypes: HIV-1 and HIV-2. Among these strains, HIV-1 is the most virulent and pathogenic. Advanced diagnostic methods are exploring new ways of treatment and contributing in the reduction of HIV cases. The diagnostic techniques like PCR, rapid test, EIA, p24 antigen, and western blot have markedly upgraded the diagnosis of HIV. Antiretroviral therapy and vaccines are promising candidates in providing therapeutic and preventive regimes, respectively. Invention of CRISPR/Cas9 is a breakthrough in the field of HIV disease management.

Abstract
Previous studies performed in Kenya have suggested that the C868T single nucleotide polymorphism (SNP) in CD4 increases the risk of HIV-1 acquisition; however, no relevant study has been conducted in China. To evaluate the influence of this SNP on risk of HIV-1 infection in a Chinese population, the CD4 genotype was determined by DNA sequencing in 101 HIV-1 patients and 102 healthy controls. No significant differences in the genotype and allele distributions of this polymorphism were observed among the patient and control groups. Additionally, binary logistic regression analyses adjusted by age and gender revealed that the C868T polymorphism was not associated with risk of HIV-1 infection. Furthermore, when analyses of genotype and allele frequencies were stratified by gender, similar nonsignificant results were found. Our study demonstrates a null association between the CD4 C868T polymorphism and an individual's susceptibility of HIV-1 acquisition in a Chinese population. Further studies are warranted to confirm these results.

Abstract
The C868T single nucleotide polymorphism in the CD4 receptor encodes an amino acid substitution of tryptophan for arginine in the third domain. Previous studies suggest that C868T increases the risk of HIV-1 acquisition; however, the influence of this single nucleotide polymorphism (SNP) on disease progression has not been established. The presence of the C868T polymorphism was not statistically significantly associated with HIV-1 disease progression outcomes in a cohort of postpartum Kenyan women.

Abstract
HIV-1 entry into cells is mediated by interactions between the envelope (Env) gp120 and gp41 proteins with CD4 and chemokine receptors via an intermediate called the viral fusion complex (vFC). Here, mAbs were used to find the dynamic changes in expression of antigenic epitopes during vFC formation. A CD4-specific mAb (R275) and anti-vFC mAbs, designated F12-1, F13-6 and F18-4 that recognize the epitopes only appeared by the co-culture of env-transfected 293FT and CD4-transfected 293 cells, were developed by immunizing ganp-gene transgenic mice with an vFC-like structure formed by the same co-culture. The epitopes recognized by the mAbs appeared at different time points during vFC formation: F18-4 appeared first, followed by F13-6, and finally F12-1. The anti-vFC mAbs had little effect on vFC formation or virus neutralization; however, interestingly F12-1 and F18-4 increased exposure of the OKT4-epitope on the domain 3 in the extracellular region of CD4. R275, which recognizes the epitope closely associated with the OKT4-determinant on the domain 3, showed the marked inhibition of vFC formation and viral neutralization activity. The Ab binding to the epitopes appeared during viral membrane fusion might reinforce the appearance of the target epitopes for effective neutralization activity.

Abstract
The C868T single nucleotide polymorphism (SNP) in the CD4 receptor encodes an amino acid change that could alter its structure and influence human immunodeficiency virus (HIV-1) infection risk. HIV-1-infected pregnant women in Nairobi were followed with their infants for 1 year postpartum. Among 131 infants, those with the 868T allele were more likely than wild-type infants to acquire HIV-1 overall [hazard ratio (HR) = 1.92, 95% confidence interval (CI) 1.05, 3.50, P = 0.03; adjusted HR = 2.03, 95% CI 1.03, 3.98, P = 0.04], after adjusting for maternal viral load. This SNP (an allele frequency of approximately 15% in our cohort) was associated with increased susceptibility to mother-to-child HIV-1 transmission, consistent with a previous study on this polymorphism among Nairobi sex workers.

Abstract
The ovine CD4 cDNA sequence from four sheep sources (Australian Merino, Indonesian Thin Tail, Canadian cross bred, Prealpes du sud) predicts a protein of 455 residues with position 130 in the V2 domain exhibiting a W instead of C suggesting that, like the white whale, dog and cat sequences, sheep CD4 contains only two disulphide bonds. The sequence shows 73% amino acid identity and 83% nucleotide identity to a CD4 sequence from the white whale and significant identity to a partial sequence (314 residues) of bovine CD4 (87% amino acid identity, 93% nucleotide identity). Phylogenetic analysis showed that the ovine CD4 sequence forms a clade with the pig, white whale, dolphin, dog and cat CD4. Two forms of ovine CD4 were identified which differ by a single base pair (T/C) in their cDNA sequence at position 622. This polymorphism is also present in sheep genomic DNA in Hardy-Weinberg equilibrium, suggesting that at least two alleles of CD4 exist in the ovine genome with no selection for a particular allele. This polymorphism changes the first codon position of amino acid 183 and results in a Pro/Ser substitution in the N-terminal region of domain 3 of the CD4 protein.

Abstract
A case of OKT4 epitope deficiency referred for investigation with suspected immunodeficiency is described. Flow cytometry analysis of OKT4 epitope deficiency in a study group of healthy black children showed different manifestations of the lack of OKT4 epitope; a complete lack of OKT4+CD4+ peripheral blood lymphocytes (PBL) with normal numbers of OKT4A+ and Leu3a-CD4+ PBL, decreased percentage OKT4+CD4+ compared with OKT4A+ and Leu-3a+CD4+ PBL, decreased fluorescent staining intensity with OKT4 and a biphasic OKT4 staining pattern associated with a reduced OKT4/Leu-3a ratio. The percentage and fluorescent intensity of OKT4+CD4+ PBL in the study group were significantly lower (P < 0.0001) than Leu-3a+CD4+ and OKT4A+CD4+ PBL. There is thus considerable risk of under-estimating the number of CD4+ cells in black South Africans if the OKT4 MoAb is used.

Abstract
"T-cell B-cell Activating Molecule" (T-BAM) is an activation-induced surface protein on CD4+ T cells that mediates a contact-dependent signal for B cell differentiation and immunoglobulin (Ig) secretion. The T-BAM protein on a helper clone of Jurkat (D1.1) was affinity purified using the anti-T-BAM mAb, 5c8. The NH2-terminal amino acid sequence of purified T-BAM was determined and found to be highly homologous to the predicted NH2-terminal sequence of a T cell ligand to the B cell CD40 molecule (CD40-L). From a D1.1 cDNA library, a clone was isolated that encodes CD40-L by sequence and drives expression of T-BAM protein on transfected cells, demonstrating that the T-BAM and CD40-L genes and proteins are identical. Moreover, transfection of T-BAM was shown to confer to non-lymphoid cells, the ability to induce B cells to upregulate the expression of surface CD23 molecules. In previous studies we showed that T-BAM was expressed predominantly on activated CD4+ and on few if any CD8+ cells. Although the current work confirms that T-BAM is largely restricted to activated CD4+ T cells, we now provide definitive evidence that T-BAM can be expressed by a small population of CD8+ T cells after activation. Importantly, a subset of CD8+ T cells do not express T-BAM after activation and this T-BAM- phenotype is maintained on certain CD8+ T cell clones. Taken together, these data unify the biology and structure of T-BAM and CD40-L and this synthesis has implications for understanding the T cell regulation of the humoral immune response.
