Context: Acquired immunodeficiency syndrome (AIDS) is an acronym for AIDS caused by a retrovirus known as human immunodeficiency virus (HIV) which breaks down the body's immune system leaving a patient vulnerable to a host of life-threatening opportunistic infections, neurological disorders or unusual malignancies. According to estimates by the World Health Organization and UNAIDS, 35 million people were living with HIV globally at the end of 2013. The first AIDS case in India was detected in 1986. Seldom studies have been conducted correlating these parameters with oral manifestations in the Indian population.
Aim: The present study was carried out to evaluate the CD4 cell counts and oral manifestations in HIV-infected and AIDS patients and to correlate them with the seronegative controls.
Methodology: This was a cross-sectional, hospital-based study on individuals who were divided into three groups, Group A consisting of 500 patients who were healthy controls without any systemic illness; Group B consisting of 500 patients who were diagnosed as HIV infected and Group C consisting of 500 patients diagnosed as AIDS patients depending on their CD4 cell counts. The permission from the Ethical Committee of the Institution as well as Superintendent of Government Hospital was obtained. Evaluation of CD4 cell counts in HIV-infected and AIDS patients was done using CyFlow Counter.
Results: The results were found to be statistically significant with the < 0.001 for the CD4 cell counts. Oral manifestations revealed varied results with different levels of significance.
Conclusion: CD4 cell counts were significantly altered in HIV-infected and AIDS patients when compared with the controls while oral manifestations revealed varied results with different levels of significance.

Background: Allergic rhinitis (AR) represents a persistent inflammatory condition affecting the upper respiratory tract, characterized by abnormal initiation of the immunoglobulin E (IgE)-mediated cascade. Follicular helper T (Tfh) cells and regulatory T (Tfr) cells are pivotal in orchestrating the development of IgE production in AR patients. IL-35, an anti-inflammatory cytokine, secreted by various cellular subpopulations.

Objective: Long-term management of people living with HIV (PLWHs) often relies on CD4 T cell counts for assessing immune recovery, yet a single metric offers limited information. This study aimed to explore the association between the CD4/CD8 ratio and T lymphocyte activities in PLWHs.
Methods: 125 PLWHs and 31 HIV-uninfected controls (UCs) were enrolled and categorized into four groups based on their CD4/CD8 ratios: extremely low ratio (ELR) group: 0.

The Nr4a nuclear hormone receptors are transcriptionally upregulated in response to antigen recognition by the T cell receptor (TCR) in the thymus and are implicated in clonal deletion, but the mechanisms by which they operate are not clear. Moreover, their role in central tolerance is obscured by redundancy among the Nr4a family members and by their reported functions in Treg generation and maintenance. Here we take advantage of competitive bone marrow chimeras and the OT-II/RIPmOVA model to show that Nr4a1 and Nr4a3 are essential for the upregulation of Bcl2l11/BIM and thymic clonal deletion by self-antigen.

T cells expressing the γδ T-cell receptor (TCR) represent a numerically small proportion of total T cells. Unlike αβ T cells they are activated by non-peptide antigens independently of MHC-presentation. γδ T cells have been recognized as a favorable prognostic marker across different tumor entities.
