Abstract

In the past 25 years, life survival curves of many countries have been remodeled owing to HIV infection. Both HIV-1 and HIV-2 can cause AIDS, yet patients infected with HIV-2 fare much better clinically and most will never experience detrimental effects of the infection. Despite over two decades of comprehensive research into vaccine development, a prophylactic vaccine is not yet realized. An essential missing link in the innovation of a successful vaccine strategy is the description of a favorable immune response that abolishes virus replication. Lessons learned from studying the role of the immune system in the long-term nonprogression characteristic of HIV-2 infection will offer insight into how a balanced immune response can protect from the destruction of the immune system associated with chronic HIV-1 infection.

Innate Immune Reconstitution in Humanized Bone Marrow-Liver-Thymus (HuBLT) Mice Governs Adaptive Cellular Immune Function and Responses to HIV-1 Infection

Wilfredo F. Garcia-Beltran, Daniel T. Claiborne, Colby R. Maldini, Meredith Phelps, Vladimir Vrbanac, Marshall E. Karpel, Katharine L. Krupp, Karen A. Power, Christian L. Boutwell, Alejandro B. Balazs, Andrew M. Tager, Marcus Altfeld, Todd M. Allen

Summary: The study found that HuBLT mice have well-reconstituted T cells with intact diversity, but exhibit weak T-cell responses to HIV-1 challenge due to a deficiency in innate immune cells, particularly monocytes. Research suggests that efforts to improve the model for HIV-1 immune response and vaccine studies should focus on restoring innate immune reconstitution.

Pulmonary Immune Dysregulation and Viral Persistence During HIV Infection

Yulia Alexandrova, Cecilia T. Costiniuk, Mohammad-Ali Jenabian

Summary: Despite successful antiretroviral therapy, people living with HIV still experience a higher rate of respiratory infections, lung cancers, and chronic lung disease. The lung mucosa, previously overlooked as an HIV reservoir site, plays a significant role in this phenomenon. Residual levels of HIV in deep tissues, combined with chronic immune activation and pulmonary inflammation, contribute to viral persistence. Factors such as smoking, gut and lung dysbiosis, and co-infections further exacerbate residual viral replication and inflammation.

Persistent T Cell Repertoire Perturbation and T Cell Activation in HIV After Long Term Treatment

Carolin T. Turner, James Brown, Emily Shaw, Imran Uddin, Evdokia Tsaliki, Jennifer K. Roe, Gabriele Pollara, Yuxin Sun, James M. Heather, Marc Lipman, Benny Chain, Mahdad Noursadeghi

Summary: In people living with HIV on long term anti-retroviral therapy, the diversity of T cell receptor repertoires remains significantly depleted, skewed by idiosyncratic clones, and associated with persistent T cell activation. Further investigation on thymic function and antigenic drivers of T cell clonal selection in PLHIV are crucial for restoring normal immune function.

Elevated Foxp3+ double-negative T cells are associated with disease progression during HIV infection

Leidan Zhang, Yuqing Wei, Di Wang, Juan Du, Xinyue Wang, Bei Li, Meiqing Jiang, Mengyuan Zhang, Na Chen, Meiju Deng, Chuan Song, Danying Chen, Liang Wu, Jiang Xiao, Hongyuan Liang, Hongxin Zhao, Yaxian Kong

Summary: Persistent immune activation plays a crucial role in CD4(+) T cell depletion and AIDS progression during HIV infection. Foxp3(+) DNT cells accumulate in untreated HIV-infected individuals and are correlated with CD4(+) T cell count, immune activation, and systemic inflammation. These findings suggest that Foxp3(+) DNT cells may serve as a potential target for controlling immune activation during HIV infection.

Cellular senescence and the host immune system in aging and age-related disorders

Yvonne Giannoula, Guido Kroemer, Federico Pietrocola

Summary: Cellular senescence involves cell cycle arrest, the acquisition of senescence-associated secretory phenotype (SASP), and changes in cell surface proteins influencing the recognition of senescent cells by immune effectors. Excessive or insufficient senescent cell generation can contribute to pathological aging. Mechanisms such as immunosuppressive molecule expression and secretion of factors attracting immune cells into the microenvironment allow evasion of immune destruction. Immune interventions can target these mechanisms and stimulate an immune response against senescence-associated antigens.

Interferon ? facilitates anti-HBV cellular immune response in a B cell-dependent manner

Shihong Zhong, Qiong Li, Chunhua Wen, Yifan Li, Yang Zhou, Zihan Jin, Guofu Ye, Yanda Zhao, Jinlin Hou, Yongyin Li, Libo Tang

Summary: The objective of this study was to investigate the role of B cells in IFN-alpha-mediated anti-HBV cellular immunity. The results showed that B cell depletion impaired the function of T cells and delayed HBV clearance. IFN-alpha treatment enhanced the response of HBV-specific CD8+ T cells, but this effect was lost in B cell-deficient models. These findings suggest that IFN-alpha orchestrates protective HBV-specific cellular immunity in a B cell-dependent manner.

Summary: This study aimed to evaluate the heterogeneity of early ex vivo immune responses during sepsis. The results showed that there were variations in ex vivo response to endotoxin, which were unrelated to immunosuppression, white blood cell count, or the causative pathogen. Patients with high ex vivo cytokine production had increased in vitro pulmonary endothelial cell permeability and attenuated in vivo host inflammation. Additionally, a four-gene signature of endotoxin response was identified, which was inversely associated with hospital mortality in a separate cohort of septic patients.

Blackwater fever and acute kidney injury in children hospitalized with an acute febrile illness: pathophysiology and prognostic significance

Andrea L. Conroy, Michael T. Hawkes, Aleksandra Leligdowicz, Ivan Mufumba, Michelle C. Starr, Kathleen Zhong, Sophie Namasopo, Chandy C. John, Robert O. Opoka, Kevin C. Kain

Summary: This study evaluates the association between blackwater fever (BWF) and acute kidney injury (AKI) in children with acute febrile illness. The results show that a history of BWF is associated with an increased risk of AKI, and AKI is associated with immune and endothelial activation, while BWF is mainly associated with endothelial activation. Severe AKI is associated with an increased risk of in-hospital death. These findings indicate the importance of recognizing and diagnosing AKI in children with febrile illness and implementing kidney-protective measures early to reduce disease progression and in-hospital mortality in this high-risk group.
