text: Cooperative disease defense emerges as group-level collective behavior, yet
how group members make the underlying individual decisions is poorly understood.
Using garden ants and fungal pathogens as an experimental model, we derive the
rules governing individual ant grooming choices and show how they produce colony-level
hygiene. Time-resolved behavioral analysis, pathogen quantification, and probabilistic
modeling reveal that ants increase grooming and preferentially target highly-infectious
individuals when perceiving high pathogen load, but transiently suppress grooming
after having been groomed by nestmates. Ants thus react to both, the infectivity
of others and the social feedback they receive on their own contagiousness. While
inferred solely from momentary ant decisions, these behavioral rules quantitatively
predict hour-long experimental dynamics, and synergistically combine into efficient
colony-wide pathogen removal. Our analyses show that noisy individual decisions
based on only local, incomplete, yet dynamically-updated information on pathogen
threat and social feedback can lead to potent collective disease defense.

text: Infections early in life can have enduring effects on an organism's development
and immunity. In this study, we show that this equally applies to developing ‘superorganisms’––incipient
social insect colonies. When we exposed newly mated Lasius niger ant queens to
a low pathogen dose, their colonies grew more slowly than controls before winter,
but reached similar sizes afterwards. Independent of exposure, queen hibernation
survival improved when the ratio of pupae to workers was small. Queens that reared
fewer pupae before worker emergence exhibited lower pathogen levels, indicating
that high brood rearing efforts interfere with the ability of the queen's immune
system to suppress pathogen proliferation. Early-life queen pathogen exposure
also improved the immunocompetence of her worker offspring, as demonstrated by
challenging the workers to the same pathogen a year later. Transgenerational transfer
of the queen's pathogen experience to her workforce can hence durably reduce the
disease susceptibility of the whole superorganism.

text: In plants, clathrin mediated endocytosis (CME) represents the major route
for cargo internalisation from the cell surface. It has been assumed to operate
in an evolutionary conserved manner as in yeast and animals. Here we report characterisation
of ultrastructure, dynamics and mechanisms of plant CME as allowed by our advancement
in electron microscopy and quantitative live imaging techniques. Arabidopsis CME
appears to follow the constant curvature model and the bona fide CME population
generates vesicles of a predominantly hexagonal-basket type; larger and with faster
kinetics than in other models. Contrary to the existing paradigm, actin is dispensable
for CME events at the plasma membrane but plays a unique role in collecting endocytic
vesicles, sorting of internalised cargos and directional endosome movement that
itself actively promote CME events. Internalized vesicles display a strongly delayed
and sequential uncoating. These unique features highlight the independent evolution
of the plant CME mechanism during the autonomous rise of multicellularity in eukaryotes.

text: "Social insect colonies tend to have numerous members which function together
like a single organism in such harmony that the term ``super-organism'' is often
used. In this analogy the reproductive caste is analogous to the primordial germ\r\ncells
of a metazoan, while the sterile worker caste corresponds to somatic cells. The
worker castes, like tissues, are\r\nin charge of all functions of a living being,
besides reproduction. The establishment of new super-organismal units\r\n(i.e.
new colonies) is accomplished by the co-dependent castes. The term oftentimes
goes beyond a metaphor. We invoke it when we speak about the metabolic rate, thermoregulation,
nutrient regulation and gas exchange of a social insect colony. Furthermore, we
assert that the super-organism has an immune system, and benefits from ``social
immunity''.\r\n\r\nSocial immunity was first summoned by evolutionary biologists
to resolve the apparent discrepancy between the expected high frequency of disease
outbreak amongst numerous, closely related tightly-interacting hosts, living in
stable and microbially-rich environments, against the exceptionally scarce epidemic
accounts in natural populations. Social\r\nimmunity comprises a multi-layer assembly
of behaviours which have evolved to effectively keep the pathogenic enemies of
a colony at bay. The field of social immunity has drawn interest, as it becomes
increasingly urgent to stop\r\nthe collapse of pollinator species and curb the
growth of invasive pests. In the past decade, several mechanisms of\r\nsocial
immune responses have been dissected, but many more questions remain open.\r\n\r\nI
present my work in two experimental chapters. In the first, I use invasive garden
ants (*Lasius neglectus*) to study how pathogen load and its distribution among
nestmates affect the grooming response of the group. Any given group of ants will
carry out the same total grooming work, but will direct their grooming effort
towards individuals\r\ncarrying a relatively higher spore load. Contrary to expectation,
the highest risk of transmission does not stem from grooming highly contaminated
ants, but instead, we suggest that the grooming response likely minimizes spore
loss to the environment, reducing contamination from inadvertent pickup from the
substrate.\r\n\r\nThe second is a comparative developmental approach. I follow
black garden ant queens (*Lasius niger*) and their colonies from mating flight,
through hibernation for a year. Colonies which grow fast from the start, have
a lower chance of survival through hibernation, and those which survive grow at
a lower pace later. This is true for colonies of naive\r\nand challenged queens.
Early pathogen exposure of the queens changes colony dynamics in an unexpected
way: colonies from exposed queens are more likely to grow slowly and recover in
numbers only after they survive hibernation.\r\n\r\nIn addition to the two experimental
chapters, this thesis includes a co-authored published review on organisational\r\nimmunity,
where we enlist the experimental evidence and theoretical framework on which this
hypothesis is built,\r\nidentify the caveats and underline how the field is ripe
to overcome them. In a final chapter, I describe my part in\r\ntwo collaborative
efforts, one to develop an image-based tracker, and the second to develop a classifier
for ant\r\nbehaviour."

text: Ants are emerging model systems to study cellular signaling because distinct
castes possess different physiologic phenotypes within the same colony. Here we
studied the functionality of inotocin signaling, an insect ortholog of mammalian
oxytocin (OT), which was recently discovered in ants. In Lasius ants, we determined
that specialization within the colony, seasonal factors, and physiologic conditions
down-regulated the expression of the OT-like signaling system. Given this natural
variation, we interrogated its function using RNAi knockdowns. Next-generation
RNA sequencing of OT-like precursor knock-down ants highlighted its role in the
regulation of genes involved in metabolism. Knock-down ants exhibited higher walking
activity and increased self-grooming in the brood chamber. We propose that OT-like
signaling in ants is important for regulating metabolic processes and locomotion.

text: Selection for disease control is believed to have contributed to shape the
organisation of insect societies — leading to interaction patterns that mitigate
disease transmission risk within colonies, conferring them ‘organisational immunity’.
Recent studies combining epidemiological models with social network analysis have
identified general properties of interaction networks that may hinder propagation
of infection within groups. These can be prophylactic and/or induced upon pathogen
exposure. Here we review empirical evidence for these two types of organisational
immunity in social insects and describe the individual-level behaviours that underlie
it. We highlight areas requiring further investigation, and emphasise the need
for tighter links between theory and empirical research and between individual-level
and collective-level analyses.
