Summary: Targeting of skin Langerhans cells (LC) may efficiently induce potent anti-HIV immune responses, serving as a promising strategy for developing effective HIV-1 vaccines. This approach demonstrates the potential of directing immune responses through specific cell targeting and may lead to the induction of protective antibodies against HIV-1.

Summary: Untreated HIV-1 infection leads to a decrease in CD4(+) T cell lymphocytes, susceptibility to opportunistic infections, and ultimately death. This study found that cytotoxic lymphocytes can target the HIV-1 Gag protein through granzyme cleavage to potentially control HIV-1 infection.

Summary: Post-translational protein modifications, particularly glycosylation, may impact T cell epitope recognition presented by HLA molecules, but this aspect has been overlooked in HIV research. Studies demonstrated that glycosylation can affect T cell recognition of viral peptides in individuals with chronic HIV infection, indicating the potential importance of glyco-epitope specific T cell immunity in understanding host immune responses against viral infections. New methodologies are needed to accurately assess the role of glycosylation in altering T cell immunity to viral infections.

Summary: In this study, 25 HLA-A0201 restricted GPC3 epitopes were predicted and 5 were identified as real-world epitopes for specific CD8(+) T cell activation. These epitopes were further confirmed to induce robust CD8(+) T cell responses and cytotoxicity targeting HepG2 cells, providing potential for the development of T cell epitope vaccines and evaluation of GPC3 specific T cell responses.

Summary: Through single-cell transcriptome analysis, different subsets of T cells in healthy and SSc skin were identified, each associated with distinct signaling pathways. A unique subset of recirculating CXCL13(+) T cells in SSc skin was discovered, expressing a T helper follicular-like gene expression signature and potentially promoting B-cell responses in the inflamed skin of patients.

Summary: Leishmania martiniquensis is a neglected cause of emerging leishmaniasis with different clinical manifestations in various countries. The study found resolution of infection in the liver but persistent infection in the spleen, with upregulation of Th1 cytokines and iNOS. High expression of IL-10 in the spleen was correlated with parasite persistence. Further research on the mechanisms of persistent infection and experimental infection in immunosuppressed murine models is needed.

Summary: This study investigated HIV-1-specific CD8(+) T cell responses in 200 Japanese HIV-1-exposed seronegative (HESN) men who have sex with men (MSM). The results showed the presence of HLA-B*51:01-restricted Pol TI8- specific and HLA-A*02:06-restricted Pol SV9-specific CD8+ T cells in two and one individuals, respectively. These HIV-1-specific T cells may contribute to suppressing HIV-1 replication in HESN-MSM individuals.

Summary: In this study, chimeric HPV:HIV VLPs were constructed by inserting HIV-1 P18I10 CTL peptide and T20 anti-fusion peptide into the HPV16 L1 capsid protein. The insertion did not affect the stability, self-assembly, morphology, and antibody reactivity of the VLPs. The chimeric VLPs induced both HPV16- and HIV-1-specific immune responses, making them a potential vaccine platform for controlling HPV16 and HIV-1 infection.

Summary: HIV infection is commonly seen in individuals infected with Mycobacterium tuberculosis (Mtb). Inflammation caused by Mtb disease could affect immune responses to HIV in these individuals. Our research reveals that HIV antibodies are broader and more potent in individuals with co-existing Mtb disease compared to those without. We speculate that the co-localization of Mtb and HIV in lymphatic tissues leads to the emergence of these potent HIV antibodies.

Summary: Peptide vaccines containing B- and T-cell epitopes, synthesized using a novel peptide welding technology (PWT), are able to generate highly immunogenic responses both in vitro and in vivo. Particularly, subcutaneous administration of B-cell epitope-based vaccines induced more potent humoral responses compared to administering the corresponding peptides alone.

Summary: This study investigates the effects of inflammatory cytokines (IC) and anti-Tat antibodies (Abs) treatment on KS-like lesions in a mouse model. The findings suggest that IC treatment exacerbates and delays the regression of KS-like lesions, while early administration of anti-Tat Abs can reduce lesion severity and accelerate regression. These results support the development of anti-Tat Ab-based therapies for AIDS-KS.

Summary: Adult vaccination programs have gained attention, and this study found that adolescents who receive an HPV vaccine have higher levels of HPV-specific IgGs, but antibody functions decline over time in both adolescents and adults. Analysis of lymphocytes revealed similar biochemical features in B-cell subsets between the two age groups. The study suggests that age-specific HPV vaccine responsiveness is mainly due to quantitative differences in immune cell precursors rather than qualitative defects in B cells.

Summary: Age-related changes in the immune system affect the ability of elderly individuals to generate effective CD8(+) T cell responses against SARS-CoV-2. Elderly individuals show a deficit in priming naive precursors into effector CD8(+) T cells, resulting in reduced diversity and expression frequency of IFN-gamma in CD8(+) T cell responses. These findings have implications for developing strategies to protect the elderly against COVID-19.
