Climate change's potential consequences have often been framed as “x will happen by 2020.” Now that we are knocking on the door of the new decade, how accurate were those predictions?
For a start, even the Australian bush fires were predicted by science:The scientist who predicted the bushfire emergency four decades agoDr Tom Beer’s pioneering 1980s research into bushfires and climate change has, to his dismay, proved all too accurate“I would blame most of that on the lobbying”,” says Pearman, now 78. “That lobbying has been extremely powerful in a country driven by the resource sector that includes uranium, coal and gas.”'What could I have done?'

Why didn't the anti-CD19 CAR-T immunotherapies from Novartis or Kite suffer from neurotoxicity adverse events as the ones from Juno did?
Brief Background on Anti-CD19 CAR-T ImmunotherapySo far, CAR-T immunotherapy has been most successful against CD19-positive tumors such as Acute lymphoblastic leukemia - Wikipedia (specifically B-ALL). CD19 is a cell surface molecule mainly expressed by mature B cells, meaning anti-CD19 CAR-T targets B cell tumors but also normal B cells. Despite considerable differences in CAR-T constructs used in different studies (1, 2, 3, 4), specificallydifferent short-chain variable fragments, scFv (the anti-CD19 antibody variable domain) that would be expressed on the CAR-T cell surface to bind to the CD19 expressed by the B cell tumor, anddifferent stimulating elements (CD28 or 4-1BB +/- CD3 ) that would get inserted into its cell membrane to signal within,so far anti-CD19 CAR-Ts have yielded impressive anti-tumor responses in relapsed or refractory populations. This is interpreted as a considerable advance since these were patients who'd failed standard therapies.Reversible Neurotoxicities as also Fatalities have occurred in various Anti-CD19 CAR-T Immunotherapy TrialsSince such studies began, different groups, including Juno, Novartis and Kite, testing CAR-T immunotherapy for B cell cancers have reported severe side effects including CRS or Cytokine release syndrome - Wikipedia and neurotoxicity as well as fatalities.CRS ranged from low-grade to high-grade fevers, muscle pain (myalgia) and severe hypotension (5).CNS (Central nervous system - Wikipedia) involvement is striking and unexpected since it occurred even in patients without disease in CNS. Neurotoxicity symptoms ranged from Ataxia - Wikipedia (lack of coordination), confusion and delirium to speech loss (aphasia), hallucinations, headaches, seizures (3, 4, 6, 7, 8, 9).While different studies reported anti-CD19 CAR-T associated-neurotoxicities in 13 to 53% of patients (10), they were reversible with speedy admission into critical care and aggressive management.Juno's ROCKET trial: Too Many Fatalities, All from Cerebral Edema. Why: Patient selection criteria and/or CAR-T construct and/or dose?Juno's ROCKET trial was different because it had far more fatalities and all from the same cause, cerebral edema, something previously unreported. Juno Therapeutics first reported 3 fatalities among enrolled patients with resistant/refractory B-ALL (11).Some additional background is necessary at this point. Early in tests of CAR-Ts, scientists observed that depleting patients of lymphocytes (aka lymphodepletion or conditioning) seemed to improve clinical response. Speculation is reducing patient's own circulating lymphocytes prior to infusing them with CAR-Ts reduces competition for cytokines such as IL-7 and IL-15 that CAR-Ts need to survive and expand. Accordingly, patients in Juno's ROCKET study also received conditioning consisting of Fludarabine - Wikipedia / Cyclophosphamide - Wikipedia, a nucleoside analog and an alkylating agent, respectively.FDA put this trial on hold after 3 patients died but then lifted the hold in a record short time, allowing it to resume after removing Fludarabine alone, implying it was the source of increased neurotoxicity. However, two more deaths occurred even after this modification in the conditioning regimen, which led to the FDA stopping this trial.It's difficult to decipher what led to these fatalities since all the relevant factors aren't (yet) in the public domain. However, comparing variables between different trials helps narrow down options (see below from 12) to patient selection and CAR-T construct and dose.Specifically, was there something different about their patient selection criteria and CAR-T construct, and did they use a different perhaps larger dose? This is becauseConditioning regimen of Fludarabine/Cyclophosphamide is commonly used in such trials with no reports of similar problems so that's out as a probable cause.Juno used autologous CAR-T cells (derived from patients themselves) as did Novartis and Kite.Juno used a similar CAR-T construct to the one currently being used by Kite in its anti-CD19 CAR-T trial (13). However, Juno tested it for ALL while Kite's ongoing trial is against non-Hodgkin's lymphoma (NHL). Safe in NHL (at least as of Aug 2017) but not in ALL patients would be an obvious speculation, and determining what the difference entails would be an obvious question to explore.Novartis (14) and Fred Hutchinson Cancer Research Center (15) are using a different CAR-T construct against ALL.Key difference is the signaling domain in their CAR-T is derived from 4-1BB while Juno and Novartis use one derived from CD28 (see below from 12).Studies suggest the CD28 signaling domain enhances anti-tumor activity (16) while the 4-1BB signaling domain confers longer persistence (16, 17).Though the Novartis (14) and FHCRC (15) trials are still ongoing, they already report high percentages of 82 (24 of 29) (18) and 93% (27 of 29) (19), respectively, complete response, which is disappearance of all clinical evidence of disease. No reports yet (as of Aug 2017) of fatalities due to cerebral edema.Unfortunately, patient selection criteria and CAR-T dose Juno used in their ROCKET trial aren't yet available in the public domain (as of Aug 2017) so conclusions about their role can only be speculative.Dose is an especially interesting consideration since one FHCRC study (19) done in collaboration with and funded by Juno showed a correlation between CAR-T cell dose and time of peak CAR-T expansion.What was additionally interesting about this study is that even though they infused CD4 and CD8 CAR-T cells at a 1:1 ratio, they found higher absolute numbers of CD8s at the peak of expansion.Since activated CD8 Cytotoxic T cell - Wikipedia are presumably the effector cells that actually kill the tumor cells, whether dose-dependent expansion of this type of 2nd generation CD8 CAR-Ts could contribute to cerebral edema in relapsing/refractory B-ALL at the dose Juno used in its ROCKET trial is a possibility to consider.Bibliography1.

Are there tricks to get bacteria to uptake nanoparticles?
Several types of nanoparticles, namely, liposomes, polymeric nanoparticles, solid lipid nanoparticles, dendrimers, appear to be taken up by bacteria. These structures have been explored mainly for their capacity to more efficiently deliver antibiotics. I highlight the few studies that directly compared bacterial uptake/activity of 'nanoparticled' cargo versus cargo alone. Key details that enhance bacterial nanoparticle uptake are italicized.From 1LiposomesLiposomes are small spherical vesicles with phospholipid bilayer walls, usually composed of an amphipathic lipid such as phosphatidylcholine. Incorporating cholesterol increases the membrane's rigidity. Liposomes encapsulate an aqueous space ranging from about 30 to 10000 nm in diameter.From 2Liposomes directly fuse with bacterial membranes, releasing their contents either within the bacterial cell membranes or into its interior. This can improve antibiotic delivery into the bacterial cells, side-stepping bacterial drug-resistance mechanisms such as bacterial membrane impermeability/low permeability or efflux systems (3).From 1Cationic liposome formulations bind more efficiently to skin-associated bacteria, Staphylococcus epidermidis and Proteus vulgaris (4).Liposome-encapsulated oleic acid was bactericidal against MRSA at a 12-fold lower concentration (5) compared to free oleic acid.Liposome-encapsulated Polymyxin B or vancomycin and teichoplanin had better antibacterial activity against drug-resistant Pseudomonas aeruginosa and MRSA, respectively (1). These liposomes also caused bacterial membrane lipid deformation suggesting they fused with it.Skin-associated Propionibacterium acnes (P. acnes). Lauric acid, a free fatty acid showed stronger anti-bacterial activity compared to palmitic and lauric acid. However, lauric acid is poorly water soluble, which limits its use in acne treatment. A study of lauric acid liposome formulation (LipoLA) showed it fused with P. acnes membranes, releasing lauric acid within and killing the bacteria (6).Metal liposomes: Metal matters. Platinum, zinc and titanium enter bacteria, gold doesn't.Wang et al made 16 nm gold nanospheres stabilized with citrate ions, which adhered well with the Salmonella typhimurium surface but were unable to get into the bacteria (7). A comparison of gold and platinum nanoparticles (8) showed the former interacted with Salmonella enteritidis but did not get inside, whereas platinum nanoparticles were observed inside the bacteria.Using flow cytometry (9), dynamic light scattering and transmission electron microscopy (10), Ashutosh et al found that Salmonella typhimurium directly uptake zinc and titanium nanoparticles.Key detail? A mammalian liver component called S9 enhances this metal nanoparticle uptake by bacteria. Experimental studies used either rat- or mouse-liver derived fraction S9. What is the role of this liver S9 fraction? It could supplement metabolic enzymes such as cytochrome P450 (10), enhance the formation of nanoparticle micelles facilitating uptake (11) or serve as a protein coating for the nanoparticles, again facilitating uptake (12).I won't cover silver nanoparticles since ionic silver is largely toxic to bacteria, and used as an antimicrobial agent itself.Polymeric nanoparticlesZhang, L., et al. (1) describe the advantages of polymeric nanoparticles for bacterial deliveryThey are structurally stable and can be synthesized with greater size precision.They have functional groups that can be chemically modified. Lectin, a protein that binds to bacterial cell wall carbohydrates, is frequently used for targeted antimicrobial delivery of polymeric nanoparticles. Lectin-conjugated polymeric nanoparticles containing gliadin specifically bound to Helicobacter pylori cell wall carbohydrate receptors and released the antimicrobial agent into the bacteria (13).Zhang et al describe two major types of polymeric nanoparticles for antimicrobial drug delivery. One is formed via spontaneous self-assembly of diblock copolymers consisting of hydrophilic and hydrophobic parts. The hydrophobic part forms the polymeric core holding the cargo while the hydrophilic part protects the core from degradation. The length of the hydrophobic chain controls the rate of cargo release. Biodegradable polymers such as poly(lactic acid) (PLA), poly(glycolic acid) (PGA), poly(lactide-co-glycolide) (PLGA), poly (?-carprolactone) (PCL), and poly(cyano- acrylate) (PCA) are used to form the hydrophobic polymeric core, while polyethylene glycol (PEG) is most commonly used as the hydrophilic part. The hydrophobic nature of the nanoparticle core allows polymeric nanoparticles to carry and deliver poorly water soluble cargo.In the other type of polymeric nanoparticle, linear polymers such as polyalkyl acrylates and polymethyl methacrylates form nanocapsules by emulsion polymerization. The cargo, antibiotics for example, are either absorbed or covalently conjugated to the nanoparticle surface.The caveat with covalent linkage is the need to empirically assess case-by-case whether the linkage inactivates cargo activity. For example, Abeylath et al found that covalent linkage inactivated penicillin but not beta-lactam or ciprofloxacin (14).Nanoparticles using poly (lactide-co-glycolide) [PLGA] loaded with antibiotics such as gentamicin (15), azithromicin and clarithromicin (16, 17) were more effective than corresponding intact antibiotic against Salmonella typhimurium. It's possible this is due to such nanoparticles adhering better to the bacteria. Dillen et al reported adhesion of PLGA containing cationic Eudragit nanoparticles to S. aureus (18). Bacterial cell walls tend to be negatively charged (19) so exploiting such electrostatic interactions helps bacterial nanoparticle uptake (20). PLGA has many other advantages including low toxicity, cargo flexibility, easy synthesis, precision engineering for surface properties (20).Solid lipid nanoparticlesLipid + surfactants for emulsification. Lipids can be free fatty acids such as palmitic, decanoic or behenic acids, or triglycerides such as trilaurin, trimyristin, or tripalmitin, or steroids such as cholesterol. Emulsifiers include soybean lecithin, phosphatidylcholine. Solid lipid nanoparticles have many advantages over other nanoparticles including greater cargo stability, bothhydrophilic and lipophilic cargo can be loaded, no need for organic solvents, greater precision in controlled cargo release and targeting, and improved bulk production.DendrimerA dendrimer is a polymer structure with enhanced surface area-to-volume ratio owing to extensive branching around a core unit. When a dendrimer has a high concentration of positively charged quaternary ammonium compounds on its surface, they bind more efficiently to negatively charged microbial cell walls. This increases bacterial membrane permeability, letting more dendrimers inside the bacteria (1, 21).I could not find a single study that directly compared cargo alone versus solid lipid nanoparticle- or dendrimer-encapsulated cargo uptake by bacteria.BibliographyZhang, L., et al.
