Summary
Dendritic cells (DCs) are crucial in early HIV infection by capturing the virus and efficiently transferring it to CD4(+) T cells. This review examines DC subsets in sexual mucosa and their role in HIV transmission, including colonic transmission.
Area of Science:
- Immunology
- Virology
- Cell Biology
Background:
- Dendritic cells (DCs) are key immune sentinels at mucosal entry points.
- DCs express specific C-type lectin receptors for pathogen detection.
- DCs play a critical role in the initial establishment of HIV infection.
Purpose of the Study:
- To review dendritic cell subsets in human sexual mucosa.
- To explore DC interactions with HIV, including uptake and transfer mechanisms.
- To discuss recent advances in understanding HIV transmission in the colon.
Main Methods:
- Literature review of dendritic cell subsets and HIV interactions.
- Analysis of mechanisms of HIV uptake by DCs.
- Examination of viral trafficking through DCs to T cells.
Main Results:
- DCs are among the first cells to encounter HIV.
- HIV transfer from DCs to CD4(+) T lymphocytes is highly efficient.
- Research is expanding to include colonic HIV transmission, not just vaginal.
Conclusions:
- DCs are critical for efficient HIV transmission to target CD4(+) T cells.
- Understanding DC subsets and their interactions is vital for HIV prevention strategies.
- Further research into colonic HIV transmission is warranted.

Antigen Presenting Cells
The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

Immune Response Against Viral Pathogens
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

T Cell Activation and Clonal Selection
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
