Picking up where @rita_rebollo left, we spent a couple of years annotating and analyzing the rest of the rice #weevil #genome (ok, the 15% left after removing repeats)! All info presented here is on the huge Additional file 2 in @BMCBiology doi.org/10.1186/s12915… 1/n
@VargasChavezC and @gabaldonlab performed a comprehensive #phylogenomic analysis of the rice #weevil and found that this insect has a high gene expansion rate when compared to other beetles. 2/n 
With the invaluable help of the SymT group from @INRAE_UMR_BF2I we have also reconstructed the #metabolic pathways from both #symbiotic partners. Specific losses of enzymes in the #weevil genome are limited while its #endosymbiont has suffered much more degradation. 3/n

Cool history in this article 👉 But, IMO, #immunology will not “come of age” until it becomes common practice to study the human #immune response in concert w/ the genetic + metabolic activity of the body’s microbial/viral ecosystems
For example, we should study T cell #immunotherapies in concert with the activity of #tumor-associated microbiomes☝️ This study is a good example of how that trend has potential: cancerdiscovery.aacrjournals.org/content/early/…
We also now realize that billions (trillions?) of #phages persist in human tissue/blood 👉 And certain phages can modulate innate #immunity via phagocytosis and cytokine responses..+ adaptive immunity via effects on antibody production: ncbi.nlm.nih.gov/m/pubmed/30585…
THIS 👉 #Mitochondria play a role in helping white blood cells target human #pathogens☝️Below, mitochondria-derived vesicles delivered #antimicrobial reactive oxygen species to control phagosome-localized S. aureus (a #bacterial infection)
So let’s add #mitochondria to the growing list of human organelles/proteins/pathways recently shown to have #antimicrobial activity 👉 Other compounds already on that list include #amyloid beta, alpha-syn, PrP, #HMOs etc☝️More context here: microbeminded.com/2018/12/30/myf…
Also #mitochondria are derived from #bacterial ancestors, and can become infected by a range of viral/bacterial #pathogens 👉 Suggests mitochondria’s antimicrobial activities may be defense mechanisms that stem from their #evolutionary history as a free-living organisms
“Missing #microbes” are a factor in the development of chronic #inflammatory disease 👉 But personally, I’m more concerned about the fact that many aspects of modern living are driving a rise in “missing #immunity” and the consequent survival of “additional persistent #pathogens”
Here’s an example 👉 #Formula feeding is often associated w/ increased chronic #disease incidence☝️ Meanwhile, #breast milk has a #microbiome, but is ALSO filled w/ antimicrobial compounds + metabolites that play a key role in the immune’s system’s ability to manage #infection
This team found that interactions b/t neonatal #saliva and #breast milk released #antimicrobial compounds including H202☝️These compounds inhibited growth of a range of human pathogens: nature.com/articles/s4159…
