Harris, 2013; Rogers, Mastroeni, Leonard, Joyce, & Grover, 2007; Stertz,

2. NEUROIMMUNE MODULATION OF SYNAPTIC
FUNCTION
Manyimmune moleculesinteract with neurotransmitter systemsand
play essential roles in modulating synaptic function. As a family of
G-protein-coupledreceptorsystems,bindingofchemokinestochemokine
receptors triggers a cascade of signaling events, which subsequently modu-
late neurotransmitter release and activities of many receptors and channels.
Forexample,chemokinesCCL2andCXCL-12regulatethereleaseofsev-
eral neurotransmitters, including glutamate, GABA, and dopamine
(Heinisch & Kirby, 2010; Rostene, Kitabgi, & Parsadaniantz, 2007). The
chemokine receptor CCR2 cross-desensitizes GABAa and mu-opioid
receptors (Rostene et al., 2007). In addition, activation of CXCR4 by its
ligand CXCL-12 triggers the release of glutamate from astrocytes (Cali,
Marchaland, Regazzi, & Bezzi, 2008). Studies also demonstrated that

proinflammatorycytokinesregulatesynaptictransmissionandplasticity,and
contributetothemaintenanceofthehomeostasisofneuronalnetworks.For
example, TNFα differentially modulates trafficking of AMPA-type gluta-
mate receptors and GABA receptors (Pribiag & Stellwagen, 2013, 2014;
Stellwagen&Malenka,2006).Itregulatesthesynapticstrengthbyfacilitat-
ing excitatory synaptic transmission, while decreasing inhibitory synaptic
transmission. IL-1β signaling modulates long-term potentiation (Avital
etal.,2003;Morietal.,2014).TypeIMHCregulatesneuraldevelopment
and activity-dependent synaptic function (Shatz, 2009). In addition, as
the key component of the neuroimmune system, microglia dynamically
detect the brain environment, even at the resting state, and contribute to
postnatal development, neuroplasticity, and circuit function (Kettenmann,
Kirchhoff, & Verkhratsky, 2013; Parkhurst et al., 2013; Tremblay et al.,
2011;Wake,Moorhouse,Miyamoto,&Nabekura,2013).Itbecomesclear
that the bidirectional communication between neuron and microglia plays
important roles in both normal brainfunction andneurobiological diseases
(Kettenmann et al., 2013; Miyamoto, Wake, Moorhouse, & Nabekura,
2013; Pannell, Szulzewsky, Matyash, Wolf, & Kettenmann, 2014;
Schafer,Lehrman,&Stevens,2013).Thus,theneuroimmunesystemmod-
ulates synaptic functions by presynaptic, postsynaptic, and neural–glial
mechanisms. Such actions of the neuroimmune system offer potential
neuroimmune mechanisms for brain functional changes associated with
alcohol and drug abuse that can alter neuroimmune signaling.
3. NEUROINFLAMMATION

of oligodendrocytes and increasing the secretion of neurotrophines. How-
ever,overactivatedmicrogliareleasesnumerousproinflammatorycytokines,
chemokines, and inducible nitric oxide synthase, which synergistically
mediate neuroinflammation. To counterbalance neuroinflammation, the
brain produces antiinflammatory factors, such as IL-10 and transforming
growthfactor-b1,toinhibitinflammatoryresponses.Itisimportanttonote
that neuroinflammation may not only be provoked by pathological condi-
tions but also can be trigged by increased neuronal activities, such as those

associated with noxious stimuli, psychological stress, and epileptic seizures
(Xanthos & Sandkuhler, 2014). In addition, neuroimmune factors mediate
neurotoxicity through various other mechanisms. Notably, chemokine
receptors CXCR4 and CCR5 are important mediators of HIV-associated
neurotoxicity (Kaul, Ma, Medders, Desai, & Lipton, 2007).
4. NEUROIMMUNE MOLECULES
IN NEURODEVELOPMENT
Neuroimmune molecules are involved in all stages of neuro-
development. They are expressed in both the developing and adult brain
andplayimportantrolesinneuro-andgliogenesis,neuronalmigration,axo-
nalpathfinding,andsculptneurocircuits(Guyon&Nahon,2007;Paolicelli
etal.,2011;Schaferetal.,2012).DysregulationofCNSimmunemolecules
attheearlystageofbraindevelopmentcausessignificantbehavioraldeficits,
which are evident by the increased risk of several neurological disorders
(Bilbo & Schwarz, 2012; Canetta & Brown, 2012; Garay & McAllister,
2010). Cytokines and chemokines play diverse roles in embryonic brain
developmentandadultneurogenesis.Forexample,gp130familycytokines
and TNFα regulate neurogenesis, gliogenesis, and neuronal survival in the
embryonicbrain(Deverman& Patterson,2009). ChemokineCXCL-12is
considered an indispensable chemoattractant for neuronal migration and
axonal path finding in the developing nervous system (Guyon & Nahon,
2007). Disruption of certain chemokine receptors causes the malformation
ofgranulecelllayersofthecerebellum,thedentategyrus,andcorticalinter-
neurons(Lu,Grove,&Miller,2002).Intheadultbrain,cytokineTNFαand
IL-6inhibitneurogenesis(Monje,Toda,&Palmer,2003),whereasthecon-
stitutive expression of IL-1β is critical for hippocampal neurogenesis. In
addition,thechemokineCXCL-12anditsreceptorCXCR4areexpressed
in the subventricular zone and regulate migration and proliferation of pro-
genitorcells(Tiveronetal.,2006).Evidencesuggeststhatalcoholexposure

5. NEUROIMMUNE FACTORS MODULATE
NEUROENDOCRINE FUNCTION
The involvement of neuroimmune molecules in the regulation of
neuroendocrine function is demonstrated in animal models and by human
conditionsofstressanddepression.Increasedlevelsofcytokinesareassoci-
ated with depression and sickness behavior (Dantzer, O’Connor, Freund,
Johnson,&Kelley,2008;Irwin&Miller,2007).Theunderlyingmolecular
andcellularmechanismsoftheseconditionsarebelievedtobeprimarilydue
to the dysregulation of the HPA axis, as well as serotonergic and dopami-
nergicsystems,byneuroimmunefactors.Avarietyofcytokineshavepotent
effectsontheHPAaxisbyregulatingthereleaseofneuropeptidesandneu-
rohormones, including corticotrophin release factor, ACTH, or cortisol
(Hueston & Deak, 2014). Conversely, glucocorticoids induced by chronic
stress have a significant impact on the neuroimmune system by regulating
expressions of cytokines in the hippocampus, the prefrontal cortex, and
the hypothalamus (Munhoz et al., 2006; Sorrells, Caso, Munhoz, &
Sapolsky, 2009). In addition, several chemokines are expressed in the
paraventricular nucleus of the hypothalamus and regulate the stress-related
neuroendocrine responses, such as the release of arginine vasopressin
(Callewaere et al., 2006; Callewaere, Banisadr, Rostene, & Parsadaniantz,
2007). One hallmark of alcohol and drug abuse and addiction is the dys-
regulated HPA axis. The ability of neuroimmune molecules in regulating
theHPAaxissuggeststhatneuroimmunemoleculesmayplayanintegrative
role in the close link between stress responses and addiction.

alcoholicbrainsandaredifferentiallycorrelatedwiththehighandlowalco-
hol consuming rodent lines (Flatscher-Bader et al., 2005; Liu et al., 2006;
Mulligan et al., 2006). In addition, polymorphisms of genes encoding
IL-1β and IL-1, as well as the gene for an antiinflammatory cytokine
IL-10, are associated with the susceptibility to alcoholism (Marcos,
Pastor, Gonzalez-Sarmiento, & Laso, 2008; Pastor, Laso, Romero, &
Gonzalez-Sarmiento, 2005). Furthermore, a study using a mouse binge
drinking model revealed a long-lasting increase of the chemokine CCL2
