it is clear that E2 can stimulate antibody production by B cells, probably by inhibiting T cell suppression of B cells

In cycling women, the largest quantities of Ig were detected before ovulation

In contrast, E2 at high concentrations leads to a suppression of B-lymphocyte lineage precursors

E2 at periovulatory to pregnancy serum levels is able to stimulate antibody secretion under healthy conditions but also in autoimmune diseases, whereas similar serum levels of E2 lead to a suppression of bone marrow B cell lineage precursors

In chronic inflammatory disorders, where B cells play a decisive role, E2 would promote the disease when autoaggressive B cells are already present, whereas chronically elevated E2 would inhibit initiation of an autoimmune disease when no such B cells are available. This might be a good reason why particularly B cell-dependent diseases such as SLE, mixed connective tissue disease (Sharp syndrome), IgA nephropathy, dermatitis herpetiformis, gluten sensitive enteropathy, myasthenia gravis, and thyroiditis appear in women in the reproductive years, predominantly, in the third or fourth decades of life

Th17 cells are thought to be the main responsible cells for chronic inflammatory tissue destruction in autoimmune diseases

IFN-γ, IL-12, and TNF were allocated to Th1 reactions

IL-4, IL-5, and IL-10 to Th2 responses

antiinflammatory T regulatory cells producing TGF-β and proinflammatory T helper type 17 cells (Th17) producing IL-17

no direct effects of estrogens on Th17 cells or IL-17 secretion have been described until now.

So-called Th17 cells producing IL-17 are the main T cells responsible for chronic inflammation.

Because IFN-γ has been allocated a Th17-inhibiting role (Fig. 1⇑), its increase by E2 at pregnancy doses and the E2-mediated inhibition of TNF must be viewed as a favorable effect in chronic inflammation

in humans and mice, E2 at periovulatory to pregnancy levels stimulates IL-4, IL-10, and IFN-γ but inhibits TNF from CD4+ T cells

In humans and mice, E3 and E2, respectively, at pregnancy levels inhibit T cell-dependent delayed type hypersensitivity

increased IL-4, IL-10, and IFN-γ in the presence of low TNF support an antiaggressive immune response

secretion of IL-1β is increased at periovulatory/proestrus to early pregnancy levels, whereas IL-1 secretion is inhibited at high pregnancy levels

The dichotomous effect of E2 on IL-1β and TNF at high and low concentrations is most probably due to inhibition of NF-κB at high concentrations

experiments with mouse and rat macroglial and microglial cells demonstrate that E2 at proestrus to pregnancy levels exerts neuroprotective effects by increasing TGF-β and by inhibiting iNOS and NO release, and reducing expression of proinflammatory cytokines and prostaglandin E2 production.

E2 at periovulatory to pregnancy levels inhibits NF-κB activation, which must be viewed as an antiinflammatory signal

It was shown that E2 concentrations equal to or above 10−10 m are necessary to inhibit NF-κB activation

important proinflammatory cytokines are typically inhibited at periovulatory (proestrus) to pregnancy levels of E2, which is evident for IL-6, IL-8, and TNF

low E2 concentrations were demonstrated to have no or even stimulatory effects

This renders a woman in the postmenopausal phase to a more proinflammatory situation

most in vitro studies demonstrated a stimulatory effect of E2 on secretion of IL-4, IL-10, and TGF-β typically at periovulatory to pregnancy levels

E2 at periovulatory to pregnancy levels has an ameliorating effect on chronic inflammatory diseases as long as B cell-dependent immunity or an overshooting fibrotic tissue repair process do not play a crucial pathogenic role. However, when the B cell plays an important role, E2 might even stimulate the disease process as substantiated by flare-ups in SLE during pregnancy

Short-term administration of E2 at pregnancy levels was shown to induce an inflammatory response specific to the lateral prostate of the castrated male rat

Studies have shown that the production of nagalase has a mutual relationship with Gc-MAF level and immunosuppression

It has been demonstrated that serum levels of nagalase are good prognosticators of some types of cancer

The nagalase level in serum correlates with tumor burden and it has been shown that Gc-MAF therapy progresses, nagalase activity decreases

It has been shown that Gc-MAF can inhibit the angiogenesis induced by pro-inflammatory prostaglandin E1

The effect of Gc-MAF on chemotaxis or activation of tumoricidal macrophages is likely the main mechanism against angiogenesis.

Administration of Gc-MAF stimulates immune-cell progenitors for extensive mitogenesis, activates macrophages and produces antibodies. “This indicates that Gc-MAF is a powerful adjuvant for immunization.”

Cancer cell lines do not develop into tumor genes in mouse models after Gc-MAF-primed immunization (29-31) and the effect of Gc-MAF has been approved for macrophage stimulation for angiogenesis, proliferation, migration and metastatic inhibition on tumors induced by MCF-7 human breast cancer cell line

The protocol included: "a high dose of second-generation Gc-MAF (0.5 ml) administered twice a week intramuscularly for a total of 21 injections.”

Yamamoto et al. showed that the administration of Gc-MAF to 16 patients with prostate cancer led to improvements in all patients without recurrence

Inui et al. reported that a 74-year-old man diagnosed with prostate cancer with multiple bone metastases was in complete remission nine months after initiation of GcMAF therapy simultaneously with hyper T/NK cell, high-dose vitamin C and alpha lipoic acid therapy

It has also been approved for non-neoplastic diseases such as autism (41), multiple sclerosis (42, 43), chronic fatigue syndrome (CFS) (40), juvenile osteoporosis (44) and systemic lupus erythematous (45).

Gc-MAF has been verified for use in colon, thyroid (38), lung (39), liver, thymus (36), pancreatic (40), bladder and ovarian cancer and tongue squamous carcinoma

Prostate, breast, colon, liver, stomach, lung (including mesothelioma), kidney, bladder, uterus, ovarian, head/neck and brain cancers, fibrosarcomas and melanomas are the types of cancer tested thus far

weekly administration of 100 ng Gc-MAF to cancer at different stages and types showed curative effects at different follow-up times

this treatment has been suggested for non-anemic patients

Studies have shown that weekly administration of 100 ng Gc-MAF to cancer patients had curative effects on a variety of cancers

Because the half-life of the activated macrophages is approximately one week, it must be administered weekly

In vivo weekly intramuscular administration of Gc-MAF (100 ng) for 16-22 weeks was used to treat patients with breast cancer

individuals harboring different VDR genotypes had different responses to Gc-MAF and that some genotypes were more responsive than others

Administration of Gc-MAF for cancer patients exclusively activates macrophages as an important cell in adaptive immunity

Gc-MAF supports humoral immunity by producing, developing and releasing large quantities of antibodies against cancer. Clinical evidence from a human model of breast cancer patients supports this hypothesis

There is also evidence that confirms the tumoricidal role of Gc-MAF via Fc-receptor mediation

It is likely that the best therapeutic responses will be observed when the nutritional and inflammatory aspects are taken together with stimulation of the immune system

it should be noted that no harmful side effects of Gc-MAF treatment have been reported, even when it was successfully administered to autistic children

The natural activation mechanism of macrophages by Gc-MAF is so natural and it should not have any side effects on humans or animal models even in cell culture

Besides the Gc-MAF efficacy on macrophage activity, it can be a potential anti-angiogenic agent (28) and an inhibitor of the migration of cancerous cells in the absence of macrophages (47).

Activating or modifying natural killer cells, dendritic cells, DC, CTL, INF and IL-2 have all been recommended for cancer immunotherapy

It has been reported that nagalase cannot deglycosylate Gc-MAF as it has specificity for Gc globulin alone

inflammation-derived macrophage activation with the participation of B and T lymphocytes is the main mechanism

macrophages highly-activated by the addition of Gc-MAF can show tumoricidal activity

Previous clinical investigations have confirmed the efficacy of Gc-MAF. In addition to activating existing macrophages, Gc-MAF is a potent mitogenic factor that can stimulate the myeloid progenitor cells to increase systemic macrophage cell counts by 40-fold in four days
