The diseases caused by disorders of the immune system fall into two broad categories: immunodeficiency and autoimmunity. Immunotherapy is also often used in the immunosuppressed (such as HIV patients) and people suffering from other immune deficiencies or autoimmune diseases. This includes regulating factors such as IL-2, IL-10, IFN-α. Infection with HIV is characterized not only by development of profound immunodeficiency but also by sustained inflammation and immune activation. Chronic inflammation as a critical driver of immune dysfunction, premature appearance of aging-related diseases, and immune deficiency.

    Papiliocin
    Papiliocin is a potent peptide antibiotic with both anti-inflammatory and antibacterial activities. Papiliocin is primarily active against Gram-negative bacteria. Papiliocin exhibits strong anti-inflammatory activity against cell, exerting its anti-inflammatory activity by inhibiting the production of NO and the secretion of TNF-α and MIP-2. Papiliocin participates in the innate defense response mechanism by inhibiting the Toll-like receptor pathway and NF-κB. Papiliocin induces apoptosis in fungal cells and increases the total level of intracellular ROS. Papiliocin acts as an effective antiseptic peptide in sepsis models. Papiliocin is useful in anti-inflammatory and antibacterial research.

RP-832c treatment significantly reduces CD206 gene expression in M2 macrophages while transiently increasing expression of TNF-α, a marker for M1 macrophages. RP-832c is used for the studies of T-cell lymphoma (CTCL) and idiopathic pulmonary fibrosis (IPF).

    RP-182 is a synthetic immunomodulatory peptide that exerts anti-tumor effects by targeting the mannose receptor CD206 (Kd = 8 μM) on the surface of tumor-associated macrophages (TAMs). RP-182 induces a conformational switch of the CD206 receptor, which activates NF-κB signaling and phagocytosis in CD206high TAMs. RP-182 has dual function: activation of canonical NF-κB signaling, triggering TNFα secretion and autocrine activation of the TNF receptor 1 (TNFR1), leading to activation of caspase 8, apoptosis, and cell death. RP-182 is used in pancreatic cancer and melanoma research.
