Recent Developments in Immune Network Theory including a concept for an HIV Vaccine

TL;DR

This paper extends the symmetrical immune network theory to include regulatory T cells and proposes a novel HIV vaccine concept using IVIG, supported by experimental predictions in animal models.

Contribution

It introduces an expanded immune network model incorporating Ts1, Ts2, Ts3, Th1, and Th2 cells and proposes a new HIV vaccine strategy using IVIG.

Findings

Extended immune network theory with new T cell types

Proposed IVIG-based HIV vaccine concept

Predicted successful outcomes in animal experiments

Abstract

The symmetrical network theory is a framework for understanding the immune system, that dates back to the mid 1970s. The symmetrical network theory is based on symmetrical stimulatory, inhibitory and killing interactions between clones that are specific for each other. Previous papers described roles for helper and suppressor T cells in regulating immune responses and a model for HIV pathogenesis. This paper extends the theory to account for regulatory T cells that include three types of suppressor cells called Ts1, Ts2 and Ts3, and two types of helper cells called Th1 and Th2. The theory leads to a concept for an HIV vaccine, namely a reagent commonly known as IVIG, to be administered in small amounts in an immunogenic form via an immunogenic route. Predictions are made for experiments in mice and macaque monkeys.
