Abstract
Peripheral blood-derived macrophages isolated from Alzheimer's disease (AD) patients have earlier been reported to demonstrate ineffective phagocytosis of amyloid-beta compared to the age-matched control subjects. However, the mechanisms causing unsuccessful phagocytosis remain unclear. Oxidative stress and the presence of ApoEε4 allele has been reported to play a major role in the pathogenesis of AD, but the contribution of oxidative stress and ApoEε4 in macrophage dysfunction leading to ineffective Aβ phagocytosis needs to be analyzed. Aβ phagocytosis assay has been performed using FITC-labeled Aβ and analyzed using flow cytometry and confocal imaging in patient samples and in THP-1 cells. Oxidative stress in patient-derived macrophages was analyzed by assessing the DNA damage using comet assay. ApoE polymorphism was analyzed using sequence-specific PCR and Hixson & Vernier Restriction isotyping protocol. In this study, we have analyzed the patterns of phagocytic inefficiency of macrophages in Indian population with a gradual decline in the phagocytic potential from mild cognitive impairment (MCI) to AD patients. Further, we have shown that the presence of ApoEε4 allele might also have a possible effect on the phagocytosis efficiency of the macrophages. Here, we demonstrate for the first time that oxidative stress could affect the amyloid-beta phagocytic potential of macrophages and hence by alleviating oxidative stress using curcumin, an anti-oxidant could enhance the amyloid-beta phagocytic efficacy of macrophages of patients with AD and MCI, although the responsiveness to curcumin might depends on the presence or absence of APOEε4 allele. Oxidative stress contributes significantly to decreased phagocytosis of Aβ by macrophages. Moreover, the phagocytic inefficiency of macrophages was correlated to the presence of ApoEε4 allele. This study also found that the Aβ-phagocytic potential of macrophage gets significantly enhanced in curcumin-treated patient-derived macrophages.

Abstract
Both desferrioxamine (DFO) and chloroquine can significantly reduce hepatic iron in experimental animals with iron overload by chelating iron from the low-molecular-weight pool or decreasing iron uptake by the transferrin-transferrin receptor cycle, respectively. However, no previous studies have investigated whether combination therapy of these two drugs would further decrease the tissue iron overload as well as iron-induced toxicity. Chloroquine administration, 15 mg/kg, 5x/week, to rats during the iron loading regime, 10 mg/kg, 3x/week for 4 weeks, significantly decreased both hepatic (54%) and macrophage iron content (24%). However when administered in combination with desferrioxamine, 10 mg/kg, 3x/week for 2 weeks at the cessation of iron loading, no further reduction of hepatic iron content was noted while the iron content of the macrophages significantly increased, possibly indicating the flux of ferrioxamine through these cells. Further studies are warranted to investigate the speciation of iron within these macrophages. Macrophages isolated from chloroquine-treated iron loaded rats showed a reduction in latent NFkappaB activation and a significant increase in lipopolysaccharide-stimulated nitrite release by comparison to these parameters in iron loaded macrophages. Co-administration of chloroquine and desferrioxamine normalised the latent activity of NFkappaB to that of control macrophages as well as increasing LPS-stimulated NO release towards control values. However, DFO alone did not have any significant effect upon either of these parameters. Such results may have important relevance for the reduced immune function of iron loaded macrophages isolated from thalassaemia patients receiving chelation therapy and their propensity to increased infection.

Abstract
We conducted kinetic studies to evaluate the effects of acute cold/restraint stress (ACRS) on both primary and secondary host resistance to Listeria monocytogenes (LM). The involvement of IL-6 also was investigated using IL-6 knockout (KO) mice on the BALB/c background. ACRS dramatically increased the serum corticosterone levels, indicating that ACRS activated the hypothalamic-pituitary-adrenal (HPA) axis. ACRS significantly inhibited host resistance to LM during a primary but not a secondary LM infection. During the primary infection, ACRS caused a significant delay in clearance of LM, loss of body weight, reduced food/water intake, and elevated levels of pro-inflammatory cytokines (IL-6, IL-1beta, and TNFalpha) and IFNgamma. ACRS IL-6 KO mice showed higher LM burdens than did IL-6 KO controls, suggesting that IL-6 is not required for the ACRS-impairment of host resistance. Elevated levels of IL-1beta and TNFalpha may compensate for the absence of IL-6 and maintain the ACRS-induced impairment, in that the serum and splenic IL-1beta and TNFalpha levels were significantly higher in infected ACRS IL-6 KO mice, but not in control IL-6 KO mice, as compared to respective wild type controls. ACRS appears to inhibit IL-6 independent mechanisms associated with innate immunity and/or the development of adaptive immunity, but these reactions are unable to modulate the more efficient secondary immune responses.
